The document discusses the history of sponsorship of television programs and the origins of internet pop-up ads. It notes that the first commercially sponsored TV show debuted in 1946 and provides examples of sponsors for British soap operas Coronation Street and Emmerdale from the late 1990s to current times. The document also explains that pop-up ads were invented in the mid-1990s by Ethan Zuckerman and originated on the Tripod.com website in the late 1990s, and that by the early 2000s most web browsers allowed users to block unwanted pop-ups.
