Today marks the anniversary of the very first television commercial which was aired on July 1, 1941. Television broadcasts were changed forever. According to Wikipedia:

The first television advertisement was broadcast in the United States at 14:29 on July 1, 1941, when the Bulova Watch Company paid $9 to New York City NBC affiliate WNBT (now WNBC) for a 20-second spot aired before a baseball game between the Brooklyn Dodgers and Philadelphia Phillies. It simply displayed a Bulova watch over a map of the U.S., with a voiceover of the company’s slogan “America runs on Bulova time!”

Thank goodness for TiVo.
