The small screen's sweetest seniors sign-off

Some of television's most well-known faces are seniors over the age of 65. While these active older adults have been influential in shaping the current state of television, two of the greatest stars in show business are set to retire soon. 

Renowned journalist Barbara Walters and late-night funny man David Letterman both recently announced their plans to leave their respective shows. Both Letterman and Walters have been some of television's most influential stars, with Letterman having starred on various television programs since 1982, while Walters has been a TV personality since 1962. Although the two are set to sign off soon, they have proven to be some of the most inspiring and influential seniors on television.

Barbara Walters set to leave "The View" May 16
Walters recently sat down with the AARP to discuss her career, reasons for leaving and retirement plans. She explained that while she has greatly enjoyed her time working as a journalist for ABC - a station at which she has worked for more than 37 years - she is excited to settle down into a less luxurious life of relaxation. The 84-year-old star explained that she's most looking forward to not having plans any more.

"Why can't I do what I'd like to do?" Walters asked, as quoted by the source. "Maybe go to a movie or a museum, maybe sleep until 9, maybe see a friend. I look forward to not having every day planned, or having to be at a certain place at a certain time."

Over the course of her impressive television career, Walters has had the chance to interview some of the nation's most interesting, influential and controversial personalities. For example, in 1999, she interviewed Monica Lewinsky following the Clinton scandal, and told the source that Lewinsky's interview has remained the most-watched since it aired.

David Letterman passes "The Late Show" torch
Talk show hosts on the late night circuit are used to swaps and new hires, but rarely do hosts leave for the long haul. Letterman, who has been on late night TV for 21 years, announced his plans to retire in 2015, Variety reported. The 67-year-old host explained that while he has had a wonderful time working on late night television, he is ready to embrace retirement living. Comedian Stephen Colbert is set to take over the program in his place. By the time Letterman retires, Colbert will be 50 years old, and will have a promising late-night career ahead of him as an engaging and witty host.
