The ratings drop likely had more to do with the length of the series than the matchup. World Series games tend to draw in more viewers as the series goes longer, and the broadcasting network usually hits the jackpot if it goes a full seven games — like last year's series.
The most-watched game this year was the clinching fifth game on Sunday night, which was seen by 17.6 million people and was the most-watched program on television last week. It had the lowest viewership since the 2014 World Series between Kansas City and San Francisco.
Between the series and Thursday night football, Fox was the week's most popular network with a prime-time average of 13.1 million viewers. NBC had 6.53 million viewers, CBS had 6.49 million, ABC had 4.2 million, Telemundo had 1.4 million, Univision had 1.3 million, ION Television had 1.2 million and the CW had 1.1 million.
Fox News Channel was the week's most popular cable network, averaging 2.56 million viewers in prime time. ESPN had 2.18 million, MSNBC had 1.5 million, Hallmark had 1.35 million and USA had 1.26 million.
ABC's "World News Now" topped the evening newscasts with an average of 8.4 million viewers. NBC's "Nightly News" had 8.2 million and the "CBS Evening News" had 5.8 million.
