Super Bowl viewers are about to get a serious case of the munchies. There are more packaged food and beverage companies advertising during the game than in any year since at least 2003, according to Ad Age research. Twelve brands in the two grocery categories are expected to air 19 ads during the game Sunday. That’s up from the nine marketers that bought ads last year and far more activity than in the early 2000s, when three or four packaged food and beverage brands typically bought time. The usual beer, soda and snack suspects will appear this year, including Coke, Pepsi, Budweiser and Doritos. But a whole new batch of family-targeted brands has ponied up, including first-time Super Bowl advertisers Cheerios and Chobani, as well as Heinz and Dannon, each making just its second big game appearance. Meanwhile, smaller challenger brands like home seltzer-maker SodaStream and Wonderful Pistachios are back after debuting last year.
