I have seen the show many times my entire life but I did not start to seriously tune in daily until 2002. I watched the show religiously from 2002 to 2006. It was my guilty pleasure. Although the past 2 seasons have just not been all that interesting. Currently, I only watch the show if I hear or see that the topic for the show is of a great interest of mine.
As much as the show is very informative and very much influential, it is equally fun and entertaining.
Oh yea. My favorite annual episode is "Oprah's Favorite Things." Who doesn't love these episodes every year?
