$1.4 billion

Estimated ad revenue for NBC from Super Bowl Sunday and the Winter Olympics in February, the network announced Thursday. The Winter Games in South Korea are expected to bring in $900 million with Super Bowl Sunday — including the TV show “This Is Us” following the game — accounting for the rest ($500 million), NBC executive Dan Lovinger said in a conference call with reporters Thursday. Lovinger, chief of ad sales for the NBC Sports Group, said the Sochi Games generated about $800 million in ad sales.
