Pan Am lost some altitude in Week 2, recruiting 7.75 million viewers — less than three-quarters of its premiere audience.

The ABC program, which took off with 10.87 million aboard, scored a 2.5 rating among 18-to-49-year-olds Sunday night, a 19 percent fall from last week's 3.1, Nielsen overnights showed.

As often happens on Sundays, numbers were skewed by a football overrun on CBS; still, the final 20 minutes of The Good Wife and then CSI: Miami grabbed 10.45 million and a 2.2 demo rating in prime time's final hour against the new 1960s drama about stewardesses.

Prime time's first hour saw the season premiere of America's Funniest Home Videos get off to its lowest-rated season debut in its history, attracting 6.44 million viewers (1.5 demo rating — a 21 percent decline), while the football overrun and 60 Minutes — featuring Andy Rooney's swan song — grabbed 17.43 million (4.5). In the same time slot, Football Night in America and animated reruns on Fox garnered 8.09 million and 5.43 million, respectively.

Despite a lopsided win by the Baltimore Ravens over the New York Jets, NBC's Sunday Night Football averaged 17.65 million fans (7.3). That was down 11 percent from 2010's Week 4 game, but still the second-highest for Week 4 in the NBC franchise's six-year history.

At 8/7c, Amazing Race had 12.99 million (3.3) vs. Extreme Makeover: Home Edition's 7.11 million (2.1).

On Showtime, Dexter slayed with its sixth season premiere — grabbing 2.2 million viewers to make it the network's top season premiere in 14 years and the network's top telecast of 2011 thus far. The series premiere of Homeland at 10/9c also broke records. The Claire Danes-headlined series netted 1.08 million viewers to become Showtime's most-watched drama series premiere in eight years (since 2001's Dead Like Me).
