Barack Obama made television history in addition to becoming the first African American democratic nominee for President of the United States on Thursday. Barack Obama's audience for his acceptance speech likely topped 40 million people, and the Democratic gathering that nominated him was a more popular television event than any other political convention in history. More people watched Obama speak from a packed stadium in Denver on Thursday than watched the Olympics opening ceremony in Beijing, the final "American Idol" or the Academy Awards this year, Nielsen Media Research said Friday. (Four playoff football games, including the Super Bowl between the Giants and Patriots, were seen by more than 40 million people.) His TV audience nearly doubled the amount of people who watched John Kerry accept the Democratic nomination to run against President Bush four years ago. Kerry's speech was seen by a little more than 20 million people; Bush's acceptance speech to GOP delegates had 27.6 million viewers. Obama's speech was the fifth-highest-rated, non-sports event watched by blacks in the last 11 years. A 30th anniversary Michael Jackson special on CBS in 2001 was on top.
