''Lassie'' is a long-running television series that originally aired from 1954 to 1973, and featured the exploits of heroic collie dog Franchise/{{Lassie}}. It is one of the archetypal HeroicPetStory series, inspiring many later imitations and parodies. In the series, Lassie was the pet of Jeff Miller (Tommy Rettig), and in later seasons Timmy Martin (Jon Provost), of "[[CommonKnowledge What's that, Lassie? Timmy's fallen down a well?]]" fame -- although a well was one of the few things Timmy ''didn't'' [[BeamMeUpScotty fall down in the course of the series]].

It may be a little hard for [[AllTropersAreYoungNerds modern tropers to really grok]], but this series was a ''big deal'' back in [[TheFifties the day]]. It was on the air at the very dawn of mass-consumption television, and it hit ''exactly'' the perfect note for young baby-boom families of the time. Lassie was one of the first true super-smash television hits, alongside shows like ''Series/LeaveItToBeaver'', that demonstrated just how potent television was as a medium - not just for storytelling, [[CashCowFranchise but for making obscene amounts of money]].

Six different dogs portrayed Lassie over the course of the series; all were owned and trained by professional trainer Rudd Weatherwax, and the five successors were descended from the original, whose off-screen name was Pal. Pal was the original Lassie, who had starred in the 1943 film ''Lassie Come Home'' (based on a novel by Eric Knight) and six sequels; when the film series ended, Weatherwax acquired the Lassie trademark (in lieu of unpaid wages, according to one account), and the television series resulted. All six dogs were actually male; male collies were thought to be more visually impressive, and less subject to seasonal shedding issues.
