Did You Know? - The U.S. television broadcast of the Super Bowl – the championship game of the National Football League (NFL) – features many high-profile television commercials, colloquially known as Super Bowl ads. The phenomenon is a result of the game's extremely high viewership and wide demographics: Super Bowl games have frequently been among the United States' most watched television broadcasts, with Nielsen having estimated that Super Bowl XLIX in 2015 was seen by at least 114.4 million viewers in the United States, surpassing the previous year's Super Bowl as the highest-rated television broadcast in U.S. history. As such, advertisers have typically used commercials during the Super Bowl as a means of building awareness for their products and services among this wide audience, while also trying to generate buzz around the ads themselves so they may receive additional exposure, such as becoming a viral video.
