Ratings: GOP Convention Way Down; CBS Wins Night

Clint Eastwood's empty-chair speech fails to make the networks' day

Coverage of the final night of the GOP convention yielded ratings blows across the board for the networks airing it Thursday night, with CBS taking a win for the night based largely on a steady "Big Brother," according to preliminary numbers.

Thursday night's ratings for all networks are likely to change due to the nature of tracking live events and preemptions from pre-season football. But as things currently stand, CBS holds first place in both the advertiser-coveted 18-49 demographic with a 1.8 rating/5 share and in total viewers with 5.7 million.
