Fast National rating for Monday, January 12, 2015.

With TV's largest audience watching the college football National Championship on ESPN, several networks opted not to air originals on Monday, allowing "The Bachelor" to carry ABC to a key demo win and "Mike & Molly" to pace CBS' overall triumph.

There have already been reports that the Oregon-Ohio State game may have drawn the largest audience in cable history, so this was all in the shadow of that.

On to the numbers...

Among adults 18-49, ABC averaged a 1.6 rating for Monday night, tops in the key demographic. CBS and NBC both averaged a 1.4 key demo rating for second. There was a big drop to FOX's 0.7 key demo rating and to the 0.3 key demo rating for The CW.

Overall, CBS and ABC both averaged a 4.5 rating/7 share, but CBS averaged 7.22 million viewers to the 6.51 million for ABC. NBC was third with 5.085 million viewers and a 3.4/5. Again, there was a big drop to FOX's 2.275 million and 1.6/2 and to the 1.095 million viewers and 0.8/1 for The CW.

8 p.m. - CBS led the 8 p.m. hour with a repeat of "The Big Bang Theory" (10.05 million and a 1.9 key demo) and a new "Mike & Molly" (9.17 million and a 2.1 key demo).
