NBC won with Who Do You Think You Are (1.2) and Dateline (1.4, 1.9).
CBS was second with Ghost Whisperer (1.5), Medium (1.4), and Miami Medical (1.3). CBS's Friday lineup has been looking rather limp since the start of the year. Miami Medical was up .3 from last week, but is still doing badly. CBS knows GW and Medium can pull 2.0+ numbers while MM has underachieved each episode.
ABC was third with Wife Swap (0.9, 1.3) and 20/20 (1.4).
Fox was last with repeats of House (0.9).
