Fox wrapped up its last upfront sale on June 3, and demand for NFL airtime by automakers was so great that the network also sold 80% of available spots Super Bowl by the end of the week, reports Anthony Crupi in Mediaweek. 

That means that the remaining Super Bowl spots will likely be sold in a "frenzied autumn rush," the article says.

The network likely increased its rates by as much as 9% over its pricing last year and sold between $1.8 billion to $1.9 billion in prime-time advertising commitments, marking Fox’s second most lucrative upfront market since it started 24 years ago.

But Fox wasn’t the only network wrapping up: The CW had also finished most of its sales by the end of the week.
