Super Bowl ads sold out at Fox

Fox sold 95% of the advertising inventory for this week’s Super Bowl by September of last year. Then it faced an unexpected and difficult challenge: Getting rid of the last 5%. After enjoying heavy demand for Super Bowl ad spots last year, Fox found itself on the precipice of great success, all while seeking eyebrow-raising prices of $6 million to more than $7 million for a 30-second slot. Then came October.
