It wasn't so long ago that we relied on TV to reach the mass market. Anyone who advertised during the Super Bowl - or "The Carol Burnett Show" for that matter - could reach a huge percentage of American households. A generation ago, advertising on ABC, NBC or CBS would get you into the majority of American homes, and command the attention advertisers today can only dream about. Back then, multi-tasking meant eating popcorn and watching "The Ed Sullivan Show" at the same time. Advertisers didn't have the battle for attention they have now.
