During his show tonight, David Letterman announced that he would be retiring in 2015. The video link is below which shows the explanation from his show tonight.
Being in high school in the late 1980s, one of the things I looked forward to was to watch The Tonight Show with Johnny Carson and then Late Night with David Letterman. The next day, my buddies and I would be repeating the jokes that we heard the night before. Those guys made me imagine about being a funny talk show host, and, in fact, influenced how I do my silly podcasts now.
Late night talk show television has changed so much since my high school days. And, I admit that I don't watch too much of it anymore. However, the influence of Carson & Letterman will be seen in late night talk show hosts of the future, and television will never be the same again....
