(my understanding is this figure also includes the simulcasts in the San Francisco and Chicago markets).
NFL Thursday Night Football: Chicago at San Francisco (NFLN; 8:21-11:23pm et)
– 3.899 million viewers
– 2.4 HH
– 1.7 A18-49
And for a sports on cable comparison:
NBA Thursday: Cleveland @ Miami (TNT; 8:16-11:10pm et)
– 2.564 million viewers
– 1.7 HH
– 1.0 A18-49
Last years’ game during the same week on NFLN did a bit better: 4.411 million, with the Mangini vs. Tom Brady-less mentor matchup between the New York Jets and New England Patriots. (as the comment below notes, last year’s version of the New York Jets also included Brett Favre). Last year the NFLN led off a week earlier than this year with a Broncos/Browns game. I don’t have handy access to those numbers, but commenter “romo” says it pulled a 1.9 household rating on November 6, 2008.
