Back in the day, Election Night was a strictly TV affair — with viewers tuning in after the polls closed to find out who won, and perhaps why.
But the major networks and cable outlets are trying to hold on to their dwindling number of viewers by incorporating their on-air coverage with online coverage. ABC, CBS and PBS will each stream part of their election-night coverage on the Web tonight. NBC and ABC plan six hours of results lasting into early Wednesday morning. The networks will involve some of the biggest and most popular websites — Google, Facebook, YouTube and Yahoo! — in delivering their versions of the news.
