NEW YORK (

TheStreet

) -- Larry King is leaving his nightly talk show on

CNN

after 25 years.

King, 76 years old, told viewers Tuesday at the beginning of his 9 p.m. show that it was "time to hang up the nightly suspenders." He said he'd keep hosting the show until a replacement was named.

In a statement, CNN, which is owned by

Time Warner

(TWX)

, said it would make an announcement in the "weeks ahead" about its 9 p.m. hour. A spokeswoman said in an email to the

TheStreet Recommends

Wall Street Journal

that there are "a number of options."

King's announcement Tuesday came a couple of weeks after he celebrated his 25th anniversary of "Larry King Live" with a week of shows interviewing President Barack Obama, LeBron James, Bill Gates and Lady Gaga.

King said he began thinking about stepping down as a plane flew him home to Los Angeles from Akron, Ohio, where he interviewed James, and he reflected on his big-name guests of the week. "I said, 'I can't top this,'" King recalled, the

reports.

Reports in the U.K. say Piers Morgan, a judge on "America's Got Talent," could be King's successor.
