NEW YORK -- Viewership maintained its slide on Day Three of the Democratic National Convention, Nielsen Media Research figures show.

From 8-11 p.m. EDT Wednesday, CNN had 1.4 million viewers, down 100,000 from the night before. MSNBC had 567,000 viewers, compared to 655,000 on Tuesday. Fox News Channel had a slight improvement with 379,000 viewers, an uptick of 2,000 from Tuesday.

This combined cable-news audience of 2.35 million viewers compares to a total of 2.15 million viewers on Day Three of the Republican National Convention in Philadelphia earlier this month.

In head-to-head coverage Wednesday from 10 to 11 p.m., NBC was first with 5.36 million viewers. CBS, in second, had an audience of 5.05 million. Third-place ABC, with 4.61 million viewers, showed a marked decline from Tuesday's audience of 5.82 million.

For the three broadcast networks, that total of 15.0 million viewers compares to 14.11 million for Day Three of the Republican convention.

PBS projected that its coverage Wednesday from 8 to 11 p.m. dipped by 100,000 viewers from Monday and Tuesday, to 2.9 million. This compares to 2.5 million viewers for the Republican convention.

Cable's noncommercial C-SPAN, which also aired the conventions, does not measure its audience.
