He is the one that has been around the longest of the current late night talk show hosts, and after many years on the air, David Letterman will finally be calling it quits with CBS in 2015.

David Letterman has had his spot on The Late Show for the past 22 years, and is set to officially announce his retirement on the episode of the show that is set to air tonight. He has been on the air as a late night talk show host longer than anyone in TV history, and just passed the record set by Johnny Carson last year.

It is truly the end of an era for late night with the exit of Letterman, and it will be interesting to see who will come in to replace him. The schedule of late night talk shows already switched around a lot in the past year with Leno leaving The Tonight Show, and being replaced by Jimmy Fallon. Seth Myers took over for Fallon in his regular time.

David Letterman made his debut on The Late Show on August 3rd, 1993, and has outlasted several other talk hosts that have come and gone on other channels and time slots. He was a recipient of the Kennedy Center Honors in 2012, being hailed as “one of the most influential personalities in the history of television, entertaining an entire generation of late-night viewers with his unconventional wit and charm.”

Les Moonves, president and CEO of CBS Corporation, spoke about the situation when saying “There is only one David Letterman. His greatness will always be remembered here, and he will certainly sit among the pantheon of this business. On a personal note, it’s been a privilege to get to know Dave and to enjoy a terrific relationship. It’s going to be tough to say goodbye. Fortunately, we won’t have to do that for another year or so. Until then, we look forward to celebrating Dave’s remarkable show and incredible talents.”

A timetable for the closing of the show has not been figured out yet, but it has been decided that it will be done sometime in 2015. He will be turning 67 years old next week, and has enjoyed great success with his show over the years.

Prior to his 22 years with The Late Show, David Letterman got his start on Mary in 1978, which co-starred Mary Tyler Moore. Just a few months later, he appeared on The Tonight Show with Johnny Carson for the first time, where he would appear a total of 22 times, and become good friends with the legendary late night show.

He also hosted a couple shows before getting to the current incarnation of The Late Show, including The David Letterman Show and Late Night With David Letterman.
