AlecBaldwinFriday’s premiere of “Up Late with Alec Baldwin” on MSNBC drew 674,000 total viewers and 172,000 adults 25-54, according to data from Nielsen.

Compared to the average in that timeslot over the past few weeks, Baldwin’s show was up in both categories, although compared to only last Friday the program was down slightly in the demo.

For comparison: CNN’s “AC360 Later” averaged 347,000 total viewers and 265,000 demo viewers, while “Hannity” on Fox News averaged 1.45 million total and 336,000 demo viewers.

“Up Late” has also named Jonathan Larson executive producer. Larsen had been EP of “Up with Chris Hayes,” overseeing the transition to new host Steve Kornacki. He previously served as a senior producer on “Countdown,” a writer and producer for “AC360″ and a political producer for “The Daily Show.”
