Fast National ratings for Monday, April 8, 2013.
 
An NCAA thriller between Louisville and Michigan delivered strong ratings and lifted CBS to Monday wins in most measures, but even the national championship couldn't take a bite out of NBC's "The Voice."
 
In fact, the NCAA final barely impacted most of Monday's originals, as "Revolution," "The Following" and "The Carrie Diaries" were all basically flat.
 
Among adults 18-49, CBS averaged a 5.5 rating for Monday night, beating the 4.0 rating for NBC in the key demographic. ABC was a distant third with a 1.8 key demo rating, beating FOX's 1.6 rating and The CW's 0.3 rating in the key demo.
 
Overall, CBS averaged an estimated 15.89 million viewers and a 9.6 rating/15 share for Monday primetime. In a tight race for second, NBC averaged a 6.8/10 and 11.22 million viewers, compared to ABC's 7.5/11 and 11.08 million. There was a big drop to FOX's 3.3/5 and 5.24 million viewers and to the 797,000 viewers and 0.5/1 for The CW.
 
[Univision averaged 3.73 million viewers and a 1.5 rating among adults 18-49 for Monday night.]
 
As always with live events, CBS' ratings here reflect time period data, rather than necessarily reflecting numbers for the NCAA Championship, per se.
