Can you believe it's been 20 years since the premiere of Friends on NBC in 1994? Today marks that anniversary. The show became of the longest-running and most favorite sitcoms of all time. Most of tis stars had previously been in short-lived series. I watched nearly every season until the show ended in 2004. I own three of the seasons on DVD. The show still airs in reruns on TBS. Certainly one of the best shows of all time.
