Michelle Obama Democratic National ConventionFirst Lady Michelle Obama took over primetime last night at the Democratic National Convention in Charlotte, NC, but a lot fewer people were watching than back in 2008. Like they had for the GOP convention last week in Tampa, ABC, NBC and CBS all broadcast an hour of the convention live, and they all had double-digit drops from the comparative night of the DNC on August 26, 2008.

With Obama’s speech the big ticket on Day 1, it was NBC that won the night as it did last week at the RNC. The network earned a 1.3/4 rating, down 24% from 2008. ABC had a 0.7/2, down 36% from four years ago. And with a 0.6/2, CBS took the biggest hit, with its coverage down 45% from the comparative night in 2008. In terms of total viewers for the hour, it was a lot like Tuesday at the RNC: NBC’s coverage last night drew 5.33 millon total viewers, CBS 3.22 million and ABC 2.59 million. Based on fast affiliates estimates not being time-zone adjusted, the numbers for the networks’ live coverage are likely to change later today.

It was actually all live on NBC on Tuesday. The network also aired a two-hour America’s Got Talent (2.3/6) second semifinal, with 12 contestants cut down to three going into the finals. Barreling toward its two-night Season 7 finale next week, Talent was down 8% from last week and tied for the series’ lowest Tuesday performance to date. On Fox, which did not air the Democrats’ convention Tuesday, it was back-to-back Gordon Ramsay with Hell’s Kitchen (2.5/8) and MasterChef (2.7/7). Both series pared down to the final two contestants as they head toward their respective September 10 finales. To that end, both were down from last week’s season highs; Kitchen dropped 14%, while MasterChef dipped 4%. Fox won the night among adults 18-49 while NBC was tops in total viewers with an audience of 7.509 million.

Besides the DNC, CBS ran repeats of NCIS (1.2/4) and NCIS: LA (1.0/3). ABC had encores of The Middle (0.9/3), Last Man Standing (0.8/2), Happy Endings (0.8/2) and Don’t Trust The B—- In Apartment 23 (0.6/2).
