An unexpectedly close presidential race that led to an even more surprising victory for former reality TV star Donald Trump over Hillary Clinton blanketed TV on Tuesday night - and well into Wednesday morning.
Early primetime ratings for the broadcast networks are off nearly 10 percent from those of the 2012 election, grossing a 20.9 rating among households across the Big Four. NBC News leads in initial returns. Overnights for Nielsen's metered markets, a tentative reflection of what the final audience might be, gives NBC a 7.0 rating among households. ABC News followed with a 6.1 rating, with CBS pulling a 4.8 rating and Big Fox coverage earning a 3.0 rating. Fast Affiliate ratings, which do not reflect time zone adjustments and are even more tentative, paint a similar hierarchy with NBC top (nearly 12 million viewers) - trailed by ABC (9.7 million), CBS (8.8 million) and Fox (4.3 million).
Call time obviously plays a bit of a factor in election night ratings. In 2012, networks started proclaiming Obama the winner at 11:12 p.m. ET. It happened a little early in 2008, with the watch ending right at 11 p.m. The 2016 race didn't officially go to Trump until nearly 3 a.m. on the East Coast.
The last two elections were fairly evenly matched in terms of primetime coverage. But both of those nights, in 2008 and 2012, don't even come close to the tally of the first debate between Clinton and Trump. Per Nielsen Media, the last election night saw an average 66.8 million viewers tuning in to live coverage on the 13 networks carrying the results between 8 and 11 p.m. E.T. That was off 7 percent from the historic 2008 election, which saw 71.5 million viewers tune in to see Barack Obama become the first black President of the United States. (Nielsen included 14 networks in the tally that year.)
No matter the final tally, this certainly has been a fall for live tune-in. The three presidential debates averaged a gross 74 million viewers across the three networks airing them, the first one averaging a record-breaking 84 million. And, on the non-election front, the final game of the World Series just set a 25-year high for baseball in nabbing 40 million viewers.
Ratings updates will come throughout Wednesday, with Nielsen confirming the final sum of primetime coverage in the late afternoon.
