Teacher: Now, understand the problem? Solve this instance: Question: How long had Budweiser been in business when they first featured the Budweiser Clydesdales in a Super Bowl commercial? Passage:The beer brand Budweiser has long been a Super Bowl fixture. Its parent company Anheuser-Busch held a long-term contract with the NFL that allowed it to buy several slots of air time from the game's broadcaster each year at a steep discount, a contract that ran through Super Bowl 50; the company continues to buy multiple commercials in each game. Budweiser runs several advertising campaigns throughout each game, one of which has traditionally featured its mascots, the Budweiser Clydesdales. The Clydesdales were included in at least one Super Bowl commercial every year from Super Bowl IX in 1975 through Super Bowl LI in 2017. Budweiser's parent company Anheuser-Busch has been the most successful advertiser in the annual Super Bowl Ad Meter survey organized by USA Today, having finished first on the survey fourteen times. When USA Today held an "All-Time Ad Meter" bracket tournament in 2014, two Budweiser commercials met in the finals; the winner was a 2008 ad spoofing Rocky, which went against its 1999 ad "Separated at Birth", which featured a pair of Dalmatian puppies given to two separate owners, but eventually seeing each other again after one became a mascot dog on the Clydesdales' carriage.
