HDTV Ratings: Investigator Bane of The Good Wife

Tuesday HD dramas Grey’s Anatomy, CSI: NY and The Good Wife last night lost viewers to TV One’s new-look line-up.

Launching Undercover Boss and The Investigator on the back of Steve and Becky’s nuptials nightmare in Coronation Street paid big dividends for the network, with the British soap posting its highest 25-54 and 18-49 year-old ratings in months.

Undercover Boss built on this with 14.6% of 25-54 and 13.2% of 18-49 — viewerships that the return of The Investigator, with its controversial take on the David Bain case, lifted to an amazing 15.9% and 13.5% respectively.

It was a stunning result for TV One, and hit the season finale of The Good Wife hardest.

It already was struggling with a weak lead-in, CSI: NY, and could muster only 4.3% of 18-49 and 3.9% of 25-54.

Ironically, TV3’s crossover stunt programming of CSI: Miami, NY and the original CSI on Saturday night doubled the 18-49 viewership of movies that recently screened in the slot, opening with a 7.3% rating in the first quarter hour and peaking at 9% near the end of the three-hour block.

The news wasn’t so good for one of TV3’s biggest HD hits, Glee, which last week was down markedly in its new 8.30pm Friday slot: 8% vs 10.5% the previous week.
