Sunday's AFC Championship Game between Cincinnati and Kansas City was the most-watched conference title game in four years.
At an average of 53.124 million viewers, the ratings were an 11 percent increase over last year's AFC title game between the same teams. The Chiefs won Sunday's game 23-20 on a field goal in the final seconds.
It was the most-watched conference championship game since the New England Patriots-Chiefs AFC title game five years ago (53.9M).
The NFC title game earlier Sunday between the Philadelphia Eagles and San Francisco 49ers garnered an average of 47.50 million viewers, down 5 percent from last year's NFC title game between the 49ers and Los Angeles Rams.
However, the NFC title game still ended as the second most-watched game of the season, surpassing the 45.65 million viewers who watched the 49ers-Dallas Cowboys in the divisional round.
