Tony Romo has agreed to the largest sports analyst contract in television history to remain with CBS.

Romo will earn $17 million per season and will be for more than five seasons, putting the total value above $100 million.

ESPN would have become eligible to negotiate with Romo beginning in March. CBS anticipated ESPN bidding approximately $20 million per season.

Romo's initial deal with CBS was for approximately $10 million over three years. 

John Madden previously had the NFL's richest broadcasting deal at $8 million per year, which would be worth $14 million when adjusted for inflation.
