A strong lineup helped NBC to a victory in 18-49 on Friday, according to fast ratings data.

Ongoing gameshow Deal Or No Deal led the 8pm hour with 12.1 million viewers. Its 4.0 rating / 12 share in 18-49 was the best demo score for any network in over three years. CBS edged ahead in total viewers with Ghost Whisperer, however, which managed 12.3 million.

Following at 9, Las Vegas notched up 10.9 million and the slot's best 18-49 rating for NBC in almost two years. The show also provided a strong inheritance for new legal drama Conviction, which had 10.2 million but was topped by Numb3rs on CBS (11.8 million).
