I already showed some Democratic coverage from CBS: now here's a look back using the footage from NBC. Here's a look at the 1956 , 1968, 1976 and 1980 conventions; all footage courtesy of the Peacock itself. And you can see all the historical footage here.
Plus here's what you saw live on NBC when they covered the 1968 Democratic Convention - the first convention they covered IN COLOR! God, what a debacle of a convention this was, looking at the footage. No wonder the Democrats lost after this performance.
