Fast National ratings for Thursday, March 20, 2014.

Second Round coverage from the NCAA Tournament got off to a slow start for CBS, allowing "Scandal"-driven ABC to win the night among young viewers, while "American Idol" helped FOX eke out an overall win.

For "Scandal" it was a good week, as a big cliffhanger and the lack of "Elementary" competition led to a small bump. The news was less good for "American Idol," which fell below a 2.0 rating in the key demo.

Without CBS' in the mix, both "Community" and "Parks and Recreation" made rare visits above the 3 million viewer mark, while "Parenthood" rose above 4 million.

On to the numbers...

Among adults 18-49, ABC averaged a 2.0 rating for Thursday night, edging out FOX's 1.8 rating in the key demographic. CBS and NBC tied for a distant third with a 1.1 key demo rating, ahead of the 0.9 key demo rating for The CW.

Overall, FOX averaged an estimated 6.83 million viewers for Thursday primetime along with a 4.2 rating/7 share, nipping ABC's 6.8 million viewers, which came with a 4.7/8. CBS was third for the night with a 2.5/4 and 3.75 million viewers, followed by NBC's 2.2/4 and 3.47 million. The CW averaged 1.935 million viewers and a 1.2/2 for the night.

8 p.m. - "Hell's Kitchen" actually won the 8 p.m. hour for FOX with 5.3 million viewers and a 1.7 rating among adults 18-49, ahead of the 4.43 million viewers and 1.2 key demo rating for CBS' NCAA Tournament coverage.

10 p.m. - "Scandal" rose to 8.92 million viewers and a 2.9 rating among adults 18-49, leading ABC to 10 p.m. wins in both measures.
