NBC News was the first to project that the House of Representatives would be taken over by the Republican Party Tuesday night.
Brian WIlliams made the call at around 9:00 PM on NBC; it was called on MSNBC at the same time. It wasn't until about 12 minutes later that Fox News projected that the house would go to the GOP, and CNN reported the news at about 9:17 PM.
Interestingly, the New York Times' live-blog notes, NBC was able to make the call before polls closed in the west.
As of 9:30 PM, neither ABC News nor CBS News had projected the final makeup of the House.
