The NFL’s national television advertising revenue is up significantly this season, defying suggestions that the league is experiencing a down year.

“Through 15 weeks of the regular season to date, NFL programming has pulled in $3.7 billion for its TV networks: CBS, NBC, Fox, ESPN and the NFL Network, per iSpot.tv,” MediaPost reports. “This is up 16% over a year ago, when it was $3.1 billion. The NFL has added more ad inventory from Thursday night games this year — as well as more digital/mobile advertising inventory.”

The top traditional TV advertising categories cited in the story are generally up from a year ago, with automotive at $748.2 million (up from $706.2 million); insurance, $285.9 million (up from $184.4 million); wireless communications services, $268.2 million (up from $239.4 million); mobile device makers, 228.2 (up from $173.9 million); and quick serve restaurants, $202.4 million (up from $180.1 million).
