UPDATE, 9:28 AM: In updated Nielsen numbers, last night’s Grammy Awards rose a little higher from earlier fast national results. The 55th Grammys pulled in 28.37 million viewers on Sunday. That’s up from the 28.12 million reported earlier and still the show’s second best audience since 1993. Among the key 18-49 demographic, the Grammys also went up from earlier, achieving a 10.1 as opposed to the 10.0 reported before.

PREVIOUSLY, 8:26 AM: Not unexpectedly, the Grammy Awards last night were down from last year’s near record-high. Kicking off with a performance by Taylor Swift, the 55th Grammys (10.0/24) on CBS pulled in 28.12 million viewers Sunday. Although down from the 39.91 million who watched last year and 27% in adults 18-49, Sunday’s 8-11:30 PM broadcast is the second-best audience for the music awards show since 1993. Last year’s Grammys came 24 hours after Whitney Houston died suddenly while in Los Angeles to attend the awards show. Interest in her death and how the Grammys would react in tribute fueled viewership to its second-highest ever. Last year’s results were a 50% leap over the 2011 show’s viewership, which itself had been the best the Grammys had done in a decade. The largest Grammy audience ever was in 1984 with 43.8 million.

In the key 18-49 demo, Sunday’s Grammys results pretty much matched the 2011 show’s ratings. The 2012 Grammys drew a steller 14.1/33 in 18-49.
