The reviews from the political talking heads -- right and left -- have been mostly positive. The visuals were spectacular and riveting. History was made at Mile High Stadium in Denver last night when Senator Barack Obama accepted the nomination of the Democratic party as the first African-American presidential candidate. There were 80,000 people packed in the stadium, and now Nielsen has determined that 38 million people tuned in to watch on TV.

How impressive is that number? It's more than the opening ceremonies from the Beijing Olympics. It's also more than the 2008 Oscars and the finale of Fox's American Idol.

The networks cleared just one hour of prime time -- from 10-11 ET -- and the Democratic organizers made sure to present Obama's speech right in that slot, not drifting into the local late news.
