The overnight ratings for Season 2 Episode 2 of Who Do You Think You Are? with Tim McGraw are up over at Zap 2 It – TV By The Numbers:

The second week of NBC’s Who Do You Think You Are? thought up a 1.4 adults 18-49 rating, up 8% from last Friday.

MediaWeek is also out with its ratings info:

Also airing from 8-9 p.m. was NBC’s Who Do You Think You Are? (Viewers: #2, 6.60 million; A18-49: #2, 1.4/ 5), featuring country western singer Tim McGraw . . .

And The Futon Critic weighs in as well:

NBC (6.00 million viewers, #2; adults 18-49: 1.4, #T1) however was one of three networks to split the demo crown with week two of “Who Do You Think You Are?” (6.60 million viewers, #4; adults 18-49: 1.4, #T4) . . .

Good news – so while the actual number of viewers is lower for this episode (6.6 million viewers vs. 7.3 million) the share of the 18-49 demographic is up over last week.  Stay tuned.
