Purpose Social network sites are becoming more visual-centric. The purpose of this paper is to examine the effectiveness of visual social network sites as a marketing platform. Design/methodology/approach This paper comprises two experiments. The first experiment sought to examine the effect of social influence; while the second experiment examined the effect of image quality on the perception of quality and purchase intention. Findings The first experiment showed that social influence did not affect perceived quality or purchase intention. In the second experiment, a one-way between-groups multivariate analysis of covariance (MANCOVA) adjusting for sport involvement showed a statistically significant difference between the two groups. Respondents in the experimental group reported higher levels of perceived quality (adjusted M=3.68) and purchase intention (adjusted M=3.23) when compared to the control group’s perceived quality (adjusted M=3.12) and purchase intention (adjusted M=2.17). Research limitations/implications One of the limitations of this study is that it only examined the effects through a single social network site, i.e. Instagram. As there are other visual-centric social network sites, such as Tumblr and Pinterest, which operate slightly different from Instagram, it remains to be established how such effects vary across these social network sites. Practical implications The results suggest that social influence on Instagram is limited and marketers should invest in images of high quality when marketing on visual social network sites. Originality/value While there are many studies examining the effectiveness of marketing on social network sites, these studies have primarily focussed on earlier social network sites, such as Facebook. Newer social network sites that are more visual-centric, such as Instagram, are different from earlier social network sites and studied to a lesser extent. This study adds insights on the marketing effectiveness of visual-centric social network sites and deepens the understanding on marketing in general on social media.

The aim of this study is to examine whether sport involvement i.e. identification with the domain of sports affect satisfaction with body image in men and women. 158 respondents from a tertiary educational institution provided data on their satisfaction with their body image, level of sport involvement, and level of physical activity. Independent t-tests were conducted to compare differences between and within genders. Female respondents (n=40) who were high in sport involvement reported a significantly lower level of dissatisfaction with their body image (M=.55, SD=.78) when compared to female respondents (n=44) who were low in sport involvement (M=.84, SD=.83; t=1.65, p<.05). There was no significant difference amongst male respondents. There was also no significant difference in satisfaction with body image across groups with varying levels of physical activity. This suggests that being involved in sport can affect body image satisfaction amongst females.

Online sports gambling is a popular recreational activity. Using the Theory of Planned Behaviour as the theoretical foundation, the aim of this study was to examine for differences between gamblers and non-gamblers in terms of their attitudes, subjective norms and perceived behavioral control towards online sports gambling. 173 male students from a tertiary educational institution were recruited for this study of which 56 respondents (32%) were gamblers. A series of regression analysis revealed differences between gamblers and non-gamblers. While subjective norms and perceived behavioural control were significant predictors of gambling intentions for the gamblers group, only attitude was a significant predictor for the non-gamblers group. Further analysis showed that subjective norms had a larger effect on the gamblers group in comparison to the non-gamblers group. Physiological data from an eye tracker provided further empirical evidence that there were differences between gamblers and non-gamblers.Gamblers, perhaps because they are more familiar with gambling websites, take less time to process information. The findings from this study suggests that there are differences between gamblers and non-gamblers. To prevent problem gambling, there is a need to develop different communication messages for gamblers and non-gamblers.

Sports sponsorship is a common marketing strategy for many commercial organisations. There has been an interest in examining the effectiveness of this strategy particularly in terms of the recall rate of sponsored brands. In recent years, eye trackers have been employed to provide deeper insights in sports sponsorship research. The aim of this paper is to provide an overview of the potential contributions and methodological challenges in the use of eye trackers in sports sponsorship research. The paper will conclude with a discussion on the future directions of sports sponsorship research.
