charles osgoodCharles Osgood, host of CBS' "Sunday Morning" for the past 22 years, is stepping down at the age of 83.

CBS has not yet named a replacement for Osgood, who took over for Charles Kuralt in 1994. The network slates a special to highlight his career.

Osgood made the announcement on air, acknowledging talk that he was thinking about retiring.

“Some of you may have heard rumors lately that I won’t be hosting these ‘Sunday Morning’ broadcasts very much longer. Well, I’m here to tell you that the rumors are true,” he said. “For years now people -- even friends and family -- have been asking me why I keep doing this considering my age. I am pushing 84. It’s just that it’s been a joy doing it!"

Osgood added, “It's been a great run, but after nearly 50 years at CBS -- including the last 22 years here on 'Sunday Morning' -- the time has come and a date is set for me to do my farewell [show]."
