71 years ago, just before a Brooklyn Dodgers vs Philadelphia Phillies baseball game (July 1, 1941), Bulova watches aired the world’s first television commercial. It aired on NBC affiliate WNBT (today WNBC-4, New York). It ran 10 seconds, 5 seconds of which included the VO. http://bit.ly/1ah1w6h
So, as we begin watching the 2013 World Series this evening, while a commercial break runs between innings, remember it was Bulova that was there first.
