DraftKings and FanDuel are more likely than casinos and lotteries to have a large portfolio of professional team sponsorships. Additionally, those two brands are also more likely to advertise during sportscasts than other gambling brands. More than half of the $21.6 million that DraftKings spent on advertising over the past 12 months was earmarked for sportscasts, according to a SportsBusiness Journal analysis of iSpot.tv data. FanDuel spent about $13.5 million in sports, which represented nearly 80 percent of its overall TV ad spend.
