Ellen DeGeneres’ daytime talkshow hit an all-time ratings high Monday with the live telecast that came hours after she hosted Sunday’s Academy Awards on ABC.

The Warner Bros.-distributed syndicated talker delivered a 4.8 household rating/11 share, a full rating point higher than the show’s previous high set in 2004. The episode marked the highest-rated in the women 18-49 (2.1) and women 25-54 demo (2.7) since at least the 2008-09 season (when overnight daytime demo ratings became available).

Warner Bros. noted that DeGeneres’ social media standing, which was already formidable, took a big leap following the Oscars and the live edition of her talkshow. She gained 2.7 million new followers and 500,000 new Facebook likes for her talkshow’s page during the past two days.

DeGeneres’ courted social media attention during Sunday’s Oscarcast by tweeting a star-studded “selfie” taken with Bradley Cooper, Meryl Streep, Angelina Jolie and other stars. That missive has been retweeted more than 3.1 million times as of Tuesday afternoon, a record for a retweet.

Sunday’s Oscars also helped boost ratings for other programs, including the Monday syndicated newsmags and ABC’s “Good Morning America.”

With next-day coverage of the Oscars, “Entertainment Tonight” averaged a strong 4.9 household rating/8 share on Monday — a 40% gain over its March 2013 average. Also on the rise were “Access Hollywood” (2.9/5, up 38%), “Extra” (2.7/5, up 42%), “The Insider” (2.0/4, up 33%) and “TMZ” (1.9/4, up 19%).

The gains were even larger in women 25-54, where “ET” ballooned 67% (to 2.5/7), and was followed by “Access Hollywood” (2.0/6, up 43%), “Extra” (1.7/6, up 55%), “TMZ” (1.4/4, up 27%) and “The Insider” (1.1/4, up 38%).

Another syndicated program, talker “Live With Kelly and Michael,” swelled vs. March 2013 by 63% in households (4.9/14) with its special Oscar-centric episode.

ABC’s “Good Morning America,” which briefly relinquished its top spot in the rankings to NBC’s “Today” during the Peacock’s coverage of the Winter Olympics, dominated on Monday with its largest-ever post-Oscars Monday audience (7.127 million viewers), rising 11% from the comparable day a year ago. And in adults 25-54, “GMA’s” 2.875 million viewers was up 16% from a year ago and the best for a post-Oscars Monday since 2005.
