Fast National ratings for Tuesday, June 3, 2014.

Both "America's Got Talent" and "The Night Shift" held up fairly well in their second weeks -- single-digit drops -- and combined to help NBC dominated Tuesday night in all measures. 

On the positive side of other notables, ABC's "Celebrity Wife Swap" finale was up from last week's episode, but "Extreme Weight Loss" was down to balance it out.

The CW's "Famous in Twelve" got off to a less-than-impressive start, but that weak performance is somewhat comparatively mitigated by the continued dwindling of the audience for FOX's "Riot" and "I Wanna Marry 'Harry.'"

And CBS procedural repeats continue to outdraw nearly everything else. 

On to the numbers...

Among adults 18-49, NBC averaged a 2.4 rating for Tuesday night, doubling up the 1.2 rating for ABC in the key demographic. CBS was third with a 1.0 key demo rating, far ahead of FOX's 0.4 key demo rating and The CW's 0.3 key demo rating.

Overall, NBC averaged an estimated 9.83 million viewers and a 5.9 rating/10 share for Tuesday primetime.
