The sitcom is a classic of American television culture, and there's really no more modern classic than the television show Friends. While the show had many iconic aspects, from Chandler Bing, played by the late Matthew Perry, to Central Perk, perhaps the most lasting effect that Friends has had on American television is the relationship between Ross and Rachel. This romance is over the top in a way that many sitcom relationships before it never were. For better or for worse, the now classic relationship reshaped television in some lasting ways.
