It may be hard to believe, but tonight marks the end of the nine-year run of One Tree Hill. (Yes, this show is still on.) The final episode is its 187th, 43 more than the critically loved Buffy the Vampire Slayer (144); 59 more than Dawson's Creek (128), the show that defined the network that spoke to a generation; and 34 more than Gilmore Girls (153), OTH's sole companion in making the jump from The WB to The CW. (The only WB show whose episode count OTH does not beat is 7th Heaven, which managed to air 243 episodes. 243!!!!) When the show debuted on September 23, 2003, with a fairly simple premise — two basketball-loving, North Carolina-living half-brothers from different mothers clash on and off the court and are tormented by their truly psychotic father — and a medium-sized cast, it was almost unimaginable that it would have the legs to become one of the last remaining shows [Ed.note: Sorry, we forgot about Smallville] from the halcyon WB days of the previous decade.
