Ellen DeGeneres said she will end her long-running daytime talk show after a nearly two-decade run that established the comedian as an iconic figure in television.

Producer Warner Bros. Unscripted Television confirmed the show's ending. Warner Bros. is part of AT&T Inc.

"Although all good things must come to an end, you still have hope that the truly great things never will," Mike Darnell, the president of Warner Bros. Unscripted Television, said in an emailed statement. "It was and is an indelible piece of the television landscape, and it will be sorely missed."

Ms. DeGeneres told The Hollywood Reporter the show's next season, its 19th, will be her last. She said she is looking for a new challenge.

Known for a mix of celebrity interviews, lighthearted games and occasional dancing, Ms. DeGeneres's program has been a fixture in daytime TV. The show, which is syndicated to TV stations across the U.S., averages more than a million viewers and is a reliable generator of viral video clips. Recent guests have included comedian Eddie Murphy, TV host Michael Strahan and actor Priyanka Chopra Jonas.

Ms. DeGeneres also has a game show on NBC called "Ellen's Game of Games" that is slated to return on May 16.

Ms. DeGeneres came out as lesbian on the cover of "Time" magazine in the late 1990s and was one of the first and most high-profile openly LGBT entertainers.

Ms. DeGeneres's character in the ABC show "Ellen" also came out as lesbian around the same time as her real-life announcement. The episode was one of the most-viewed TV moments, drawing an audience of more than 36 million.

Ms. DeGeneres' daytime show, which made its debut in 2003, is one of the longest-running programs in the genre. Other such long-running shows include "the Oprah Winfrey Show," which ran nationally from 1986 to 2011, and "the Phil Donahue Show," which ran for more than two decades.

Viewership of daytime programming has suffered in recent years, part of a broader erosion in TV ratings as viewers cut the cable cord and turn to streaming.

Ms. DeGeneres's show came under scrutiny last year when BuzzFeed News reported on allegations of a toxic workplace. Ms. DeGeneres apologized to viewers on air, saying, "I learned that things happen here that never should have happened."

Ratings for Ms. DeGeneres's program started to decline after the controversy. An average of 1.47 million viewers have tuned in to each episode so far this season, according to Nielsen, a 39% decrease compared to the show's previous season.

David McGuire, executive vice president of programming and development at Warner Bros.' Telepictures production company, said in a statement that Ms. DeGeneres's show remains one of the top-rated daytime programs. He attributed some of the ratings decreases to the Covid-19 pandemic, calling Ms. DeGeneres's program "one of the longest running and most successful talk shows in history."

Workplace behavior in Hollywood has come under increased scrutiny in recent years after numerous allegations of misconduct came to light in a culture that once considered the bad behavior of executives and talent to be a cost of doing business.

Other stars of daytime TV have followed up their TV careers by pursuing opportunities in other areas of entertainment, including streaming video.

Judy Sheindlin, whose popular daytime reality show "Judge Judy" is ending, is planning to launch a new reality courtroom show called "Judy Justice" on Amazon.com Inc.'s IMDb TV ad-supported streaming service. Oprah Winfrey, the long-reigning queen of daytime talk, now presides over a media empire that includes podcasts and a streaming-TV deal with Apple Inc.

"Oprah has remained just as strong of a media force without a talk show as she was when she had one," said Wesley Hyatt, author of "The Encyclopedia of Daytime Television."
