The Baltimore Ravens’ victory over the San Francisco 49ers in the Super Bowl on Sunday appears to have set a ratings record, based on overnight numbers — though this year’s early estimates are murkier than usual due to the lengthy blackout that delayed the game for more than 30 minutes.

According to Nielsen, CBS’ coverage from 6:30 to 8:45 p.m. and 9:15 to 10:45 p.m. ET earned a 48.1 household rating/71 share, up a bit from the last two Super Bowls, which averaged just below a 48 rating. Last year’s game between the New York Giants and New England Patriots on NBC averaged an estimated 113.35 million viewers.

The preliminary overnights do not include the power outage from 8:45-9:15 p.m. ET. Sunday’s game peaked with a 52.9/75 overnight rating from 10:30-10:45 p.m. ET.

The half-hour containing the Beyonce concert at halftime earned a 48.2/71, right in line with the surrounding half-hours of football action.

Baltimore grabbed the top scores among Nielsen’s metered markets (a 59.6 rating/83 share), with host city New Orleans second (57.1/77).

Following the postgame show on CBS, rookie drama “Elementary” averaged a series-best 12.0 household rating/24 share in the metered markets from 11:15 p.m. to 12:15 a.m., and a special late Sunday airing of “Late Late Show with Craig Ferguson” (12:45-1:45 a.m.) averaged a preliminary 3.2/11.
