Ad-ding to the gambling literature: A brief overview of our recent papers on sports gambling advertising

Over the last 18 months I have been working with Dr. Hibai Lopez-Gonzalez on a project examining online sports betting and online sports betting advertising. We have already had eight papers accepted for publication and today’s blog briefly rounds up the ones that specifically relate to online sports betting. If you would like copies of them, please click on the hyperlinks. If you are unable to access them, then drop me an email and I will send you a copy (mark.griffiths@ntu.ac.uk).

Lopez-Gonzalez, H., Estevez, A. & Griffiths, M.D. (2017). Marketing and advertising online sports betting: A problem gambling perspective. Journal of Sport and Social Issues, 41, 256-272.

• In this article, online sports betting is explored with the objective of critically examining the potential impact on problem gambling of the emerging product features and advertising techniques used to market it. First, the extent of the issue is assessed by reviewing the sports betting prevalence rates and its association with gambling disorders, acknowledging the methodological difficulties of an unambiguous identification of what exactly constitutes sports-related gambling today. Second, the main changes in the marketization of online betting products are outlined, with specific focus on the new situational and structural characteristics that such products present along with the convergence of online betting with other adjacent products. Third, some of the most prevalent advertising master narratives employed by the betting industry are introduced, and the implications for problem gamblers and minors are discussed.

• Gambling disorder is known to have a negatively detrimental impact on affected individual’s physical and psychological health, social relationships, and finances. Via remote technologies (e.g., Internet, mobile phones, and interactive television), gambling has come out of gambling venues and has brought the potential for online gambling to occur anywhere (e.g., the home, the workplace, and on the move). Alongside the rise of online gambling, online gambling advertising have spread throughout all type of media. In a sample of 201 Spanish university students, the present study explored the perceived influence of online gambling advertising. More specifically it examined the Third-Person Effect (TPE), and its consequences on individuals’ willingness to support censorship or public service advertising. The findings demonstrate that despite the difference on the perception of the effects of online gambling advertising, it scarcely accounts for the behavioural outcomes analysed. On the contrary, awareness of problem gambling and, above all, paternalistic attitudes appear to explain this support

• Environmental stimuli in the form of marketing inducements to gamble money on sports have increased in recent years. The purpose of the present paper is to tackle the extended definition of the gamblification of sport using sponsorship and partnership deals of gambling, forex trading, and fantasy gaming as a proxy for assessing its environmental impact. Using data concerning sponsorship deals from English Football Premier League, the paper builds on the evidence of English football’s gamblification process to discuss the impact that the volume, penetration, and marketing strategies of sports betting might have on public health and wellbeing. Findings demonstrate that gambling marketing has become firmly embedded in the financial practices of many English Premiership football clubs. It is argued that such associations are not trivial, and that the symbolic linkage of sport and newer gambling forms may become an issue of public health, especially affecting vulnerable groups such as minors and problem gamblers. The present study is the first to explore in-depth the relationship and potential consequences and psychosocial impacts of sports-related marketing, particularly in relation to football.

Lopez-Gonzalez, H., Guerrero-Sole, F. & Griffiths, M.D. (2017). A content analysis of how ‘normal’ sports betting behaviour is represented in gambling advertising. Addiction Research and Theory, in press.

• Previous research has suggested that motives play an important role in several potentially addictive activities including online gaming. The aims of the present study were to (i) examine the mediation effect of different online gaming motives between psychiatric distress and problematic online gaming, and (ii) validate Italian versions of the Problematic Online Gaming Questionnaire, and the Motives for Online Gaming Questionnaire. Data collection took place online and targeted Italian-speaking online gamers active on popular Italian gaming forums, and/or Italian groups related to online games on social networking sites. The final sample size comprised 327 participants (mean age 23.1 years [SD=7.0], 83.7% male). The two instruments showed good psychometric properties in the Italian sample. General psychiatric distress had both a significant direct effect on problematic online gaming and a significant indirect effect via two motives: escape and fantasy. Psychiatric symptoms are both directly and indirectly associated with problematic online gaming. Playing online games to escape and to avoid everyday problems appears to be a motivation associated with psychiatric distress and in predicting problematic gaming.

• The prevalence of sports betting advertising has become a major concern for gambling regulators, particularly since the legalization of online gambling in many European jurisdictions. Although the composition of gambling advertisement narratives has received some limited attention, nothing is known regarding how betting advertisements (often referred to as ‘adverts’ or ‘commercials’) might be associating gambling with other potentially risky behaviors. The present paper examines the representation of alcohol drinking and low nutritional value food eating in sports betting advertising. By means of a mixed-methods approach to content analysis, a sample of British and Spanish soccer betting adverts was analyzed (N=135). The results suggest that betting advertising aligns drinking alcohol with sports culture, and significantly associates emotionally-charged sporting situations such as watching live games or celebrating goals with alcohol. Additionally, alcohol drinking is more frequent in betting adverts with a higher number of characters, linking friendship bonding and alcohol drinking (especially beer) in the context of sports gambling.

Lopez-Gonzalez, H., Estévez, A. & Griffiths, M.D. (2017). Controlling the illusion of control: A grounded theory of sports betting advertising in the UK. International Gambling Studies, in press.

• Sports betting advertising has arguably permeated contemporary sport consumption in many countries. Advertisements build narratives that represent situations and characters that normalize betting behaviour and raise public concerns regarding their detrimental effect on vulnerable groups. Adopting a grounded theory approach, the present study examined a British sample of sports betting advertisements (N = 102) from 2014 to 2016. The analysis revealed that individual themes aligned in a single core narrative, constructing a dual persuasive strategy of sports betting advertising: (i) to reduce the perceived risk involved in betting (with themes such as betting with friends, free money offers, humour, or the use of celebrities) while (ii) enhancing the perceived control of bettors (including themes of masculinity and sport knowledge). In addition, new technological features of sports betting platforms (e.g. live in-play betting) were used by advertisers to build narratives in which the ability to predict a sports outcome was overlapped by the ability of bettors to use such platforms, equalizing the ease of betting with the ease of winning. Based on the data analysed, it was concluded that the construction of a magnified idea of control in sports betting advertising is a cause for concern that requires close regulatory scrutiny.

Selling hope: A brief look at the advertising of online sports betting

(Please note that this article was co-written with Dr. Hibai Lopez-Gonzalez).

Marketing strategies are essential in a market environment such as online sports betting wherein product differentiation is minimal and price inelasticity robust. Business insiders widely accept that product innovation is instantly replicated across competitors, which are permanently seeking to generate, so far unfruitfully, a disruptive competitive edge. In a context where the number of licensed bookmakers is constantly growing, advertising plays a big part in luring customers who cannot tell the difference between companies. Advertising and marketing spend on sports betting has increased exponentially over the last five years in Europe and that is mirrored on the exposure to betting commercial messages of sports fans.

For instance, a 2014 report published by the Victorian Responsible Gambling Foundation estimated that viewers of the Australian Football League and the National Rugby League – the two most followed sport codes in Australia – are exposed to 10 to 15 minutes of gambling advertisements per game. Similarly, Dr. Sophie Lindsay and colleagues in a 2013 issue of BMC Public Health looked further into the environmental impact of gambling advertising in sport events. They calculated that in three rugby league matches the public had been exposed to ‘322 episodes’ of betting marketing – for example, considering an episode every time an electronic banner advertised a gambling site – which is somewhat paradoxical given in-play betting is illegal in Australia (as of mid-2016).

One of the marketing tricks is the use of the psychological bias known as the ‘representativeness heuristic’ (coined by Dr. Amos Tversky and Dr. Daniel Kahneman). Imagine the following two betting propositions concerning a soccer game: (a) FC Barcelona will lose the next match against the bottom team in the league (an extremely unlikely event, say 0.01 probability); (b) FC Barcelona will lose the next match against the bottom team in the league but (i.e. AND) Leo Messi will score at least one goal (this one an extremely likely event, for the sake of the argument, 0.99 probability). Mathematically speaking, proposition B can never be a better choice than proposition A, since P(A)=0.01 as opposed to P(B)=0.01×0.99= 0.0099. However, bookmakers understand that Messi scoring a goal is a highly representative event that can be effortlessly be retrieved from memory, transferring the representativeness to the whole betting proposition. In addition, it is plausible that representative heuristics work in conjunction with wishful thinking, overestimating the likelihood of an event based on one’s own preferences, as anecdotal evidence from betting advertisements concerning national teams participating in international competitions appear to suggest.

In a recent paper in the Journal of Sport and Social Issues, I and my colleagues (Dr. Hibai Lopez-Gonzalez and Dr. Ana Estevez) discussed two of most utilized master narratives in online betting promotions are discussed, namely skill-enhancing narratives – in which there is an overemphasis on the capacities and knowledge of the bettor – and, at the other end of the spectrum, risk-lowering narratives – which underemphasise the risks involved in betting and typically overestimate the probability of winning.

Skill-enhancing narratives: In a 2016 issue of iGaming Business magazine, Vahe Baloulian, CEO of the betting software company BetConstruct, declared that new features were there to give customers ‘a chance to feel more in control by engaging more often and making decisions’ with ‘feel’ and ‘control’ being the keywords here. The ‘feel’ component refers to a perceived non-factual sensation that lies at the heart of the advertising endeavour. The perception of control over the betting activity has been found to be a common attribute of gambling narratives in Swedish research by Dr. Per Binde, in which elements of skill have been exaggerated, as well as in televised commercials from Canada (in a 2008 paper by John McMullan and Delthia Miller in the Journal of Gambling Issues), wherein betting has been associated with the imagery of media sport communication, skills, and long-meditated strategies, while luck was downplayed.

Many betting features newly added to online platforms are said by commercials to enhance the control of the user over the outcome of the event bet upon, including more gamified experiences (where passive bettors supposedly become players), immersive betting experiences, and fantasy sports (where the player actively recruits a team). In these examples, the betting experience demands a higher involvement from the bettor, arguably resulting in a psychological transference between the active role of a bettor executing actions and the actual influence a bettor’s actions may have on the outcome of an external event. In essence, betting advertising contributes to the myth of gambling as a sport, an activity that is healthy, harmless, and that can be mastered with practice and talent.

Among the most used selling points that enhance the self-efficacy and control of the sports bettor are the narratives of masculinity. Attributes such as loyalty to the team, being a real man, and being brave enough to prove sporting knowledge have been implicit in some sports betting messages, including stereotyped gender depictions and sexualized imagery. According to recent research by Dr. Nerilee Hing and colleagues (in the International Journal of Mental Health and Addiction), the prototype sports bettor is male, young, tech-savvy, and professional, which aligns with the target audience of betting advertising. This reinforces the idea of male providers that sublimates in gambling their manly instincts for aggression, competition, and combat, as was observed in the behaviour of horserace bettors as identified in early studies.

Risk-lowering advertising: In parallel to the skill-enhancing strategies, advertising diminishes the harmful consequences of excessive betting by representing it as a risk-free activity. The combined narrative would be that of a safe environment where intelligent people possess the tools to succeed. In an attempt to lower the perceived risk inherently embedded in any betting activity, three major messages have been emphasized by advertisers: (i) betting is a perfectly normal activity; (ii) errors in betting predictions are not fatal; and (iii) betting is a social activity.

Advertising has been frequently proposed as a significant mechanism of gambling normalisation including new social media channels (see Dr. Sally Gainsbury and colleagues 2016 research in the Journal of Gambling Studies). The portrayal of gambling attitudes and behaviours in media representations as well as in real life environments promotes the idea of gambling as an intrinsic form of entertainment. This is true for all forms of gambling but sports betting presents some singular intensifiers. Unlike any other gambling form, sport instils in betting its health and sanitization attributes. Attributes such as fair competition, success through talent and perseverance, equal opportunities and big rewards, respect for nature, green and healthy habits are transmitted to betting behaviour. Celebrities deepen that connection as they have been proven to reduce the perceived risk by the public of the products they endorse. Sportspeople tell the story of young, talented risk-takers who challenged the odds but emerged successful in the end, arguably a perfect incarnation of the bettor’s own aspirational narrative.

Another marketing technique broadly employed by betting operators concerns the provision of risk-free bets. Advertisements typically offer welcome bonuses for new customers, free bonuses for loyal clientele, and money-back exceptions in multiple complex accumulated bets. All of these free offers pose a dual threat. On the one hand, the so-called free money requires bettors to engage in further betting in order to reclaim their benefits (leading to money losses in the process). On the other hand, even if it is a bona fide free bonus, problem gamblers might conceptualise betting as a riskless activity that entails no responsibilities even when done excessively.

A third main risk-lowering technique used in commercials is the representation of betting as a social form of entertainment to be conducted alongside other people. Solitary gambling, like solitary drinking, has been thought to be a determinant and/or consequence of problem gambling. However, some studies have raised the alarm about the misconception that gambling, when done in group, cannot be problematic (see the recent work of Emily Deans and her colleagues in ‘Further reading’ below). In fact, peer facilitation has been identified as a fundamental contributing factor to impulse betting, with excessive betting being more plausible when sport matches are viewed in the company of others (as shown by Mattew Lamont and colleagues in a 2016 qualitative study in Sport Management Review). Sport is a cultural product, socially consumed (watched, practiced, discussed, and bet upon). The social stigma attached to gambling habits might be shifting towards its naturalisation, a long-term process that advertising cannot carry out on its own but can certainly facilitate.

It takes all sports: A brief look at sport-related betting

Over the past year I have been carrying out research with my Spanish colleague – Dr. Hibai Lopez-Gonzalez – into problematic sports betting and sports betting advertising which has already produced a number of papers (see ‘Further reading’ below) and with many more to come. One of the issues we have faced in contextualising our work is that there is no such concept as sport-related problem gambling in prevalence surveys because problem gambling is assessed on the totality of gambling experiences rather than a single activity. For instance, in the three British Gambling Prevalence Surveys (BGPSs) conducted since 1999, sport-related gambling is subsumed within a number of different gambling forms: ‘football pools and fixed odds coupons’, ‘private betting’, and ‘other events with a bookmaker’. The 2010 BGPS (which I co-authored) included ‘sports betting’ as a category, along with ‘football pools’ (no coupons), ‘private betting’, ‘spread betting’ (which can include both sports or financial trading). In addition, the 2010 BGPS added a new category under online gambling activities to include ‘any online betting’. More recently, the Health Survey for England also introduced a new category: ‘gambling on sports events (not online)’.

Despite these limitations, some evidence can be inferred from gambling activity by gambling type. In 2014, Heather Wardle and her colleagues combined the gambling data from the Health Survey for England and the Scottish Health Survey. They reported that among adult males aged 16 years and over during a 12-month period, 5% participated in offline football pools, 8% engaged in online betting (although no indication was made about whether this only involved sport), and 8% engaged in sports events (not online). The categories were not mutually exclusive so an overlapping of respondents across categories was very likely. A similar rate was found in South Australia in a 2013 report the Social Research Centre with those betting on sports over the past year accounting for 6.1% of the adult population, an increase from the 4.2% reported in 2005.

In Spain, the Spanish Gambling Commission (Direccion General de Ordenacion del Juego [DGOJ] reported that 1.5% of the adult (male and female) population had gambled online on sports in 2015. This is a significantly lower proportion compared with the British data, although the methodological variations cannot be underestimated. Spanish data also shows that, among those who have gambled online on a single gambling type only, betting on sports is the more prevalent form with up to 66% of those adults.

In France, the data on the topic only focuses on those who gamble rather than examining the general population of gamblers and non-gamblers. Among online gamblers, Dr. Jean-Michel Costes and colleagues reported in a 2011 issue of the journal Tendances that 35.1% had bet on sports during the last 12 months. In another French study by Costes and colleagues published in a 2016 issue of the Journal of Gambling Studies, sports betting represented 16.4% of the gambling cohort, although again, the representativeness of sports betting behaviour among the general gambling and non-gambling population could not be determined.

Due to the aforementioned shortcomings in the definition of sport-related gambling, there is only fragmented empirical evidence concerning the impact of sports-related problem gambling behaviour. For instance, in 2014, Dr. Nerilee Hing noted that clinical reports indicate that treatment seeking for sports-related problem gambling had grown in Australia. In British Columbia (Canada), a 2014 survey by Malatests & Associates for the Ministry of Finance reported that 23.6% of at-risk or problem gamblers had gambled on sports either offline or online. A smaller proportion (16.2%) was found in the Spanish population screened in the national gambling DGOJ survey, except this subgroup was entirely composed of online bettors.

In a 2011 study published in International Gambling Studies with patients from a pathological gambling unit within a community hospital in Barcelona, Dr. Susana Jiménez-Murcia and her colleagues found that among those who had developed the disorder gambling online only (as opposed to those who gamble both online/offline or offline only), just over half (50.8%) were sport bettors. Those who gambled online only (on any activity) and those that only gambled online on sports events represented a small minority of the total number of problem gamblers. Overall, there is relatively little research on this sub-group of gamblers therefore I and others will be monitoring the evolution of this trend as the online gambling population grows.
