FantasmagoriebyEmileCohl,1908
FollowingthesuccessesofBlacktonandCohl,manyotherartistsbeganexperimentingwithanimation.OnesuchartistwasWinsorMcCay,asuccessfulnewspapercartoonist,whocreateddetailedanimationsthatrequiredateamofartistsandpainstakingattentionfordetail.Eachframewasdrawnonpaper;whichinvariablyrequiredbackgroundsandcharacterstoberedrawnandanimated.AmongMcCay'smostnotedfilmsareLittleNemo(1911),GertietheDinosaur(1914)andTheSinkingoftheLusitania(1918).
Theproductionofanimatedshortfilms,typicallyreferredtoas"cartoons",becameanindustryofitsownduringthe1910s,andcartoonshortswereproducedtobeshowninmovietheaters.ThemostsuccessfulearlyanimationproducerwasJohnRandolphBray,who,alongwithanimatorEarlHurd,patentedthecelanimationprocesswhichdominatedtheanimationindustryfortherestofthedecade.

Traditionalanimation
Thetraditionalcelanimationprocessbecameobsoletebythebeginningofthe21stcentury.Today,animators'drawingsandthebackgroundsareeitherscannedintoordrawndirectlyintoacomputersystem.Varioussoftwareprogramsareusedtocolorthedrawingsandsimulatecameramovementandeffects.Thefinalanimatedpieceisoutputtooneofseveraldeliverymedia,includingtraditional35 mmfilmandnewermediasuchasdigitalvideo.The"look"oftraditionalcelanimationisstillpreserved,andthecharacteranimators'workhasremainedessentiallythesameoverthepast70years.Someanimationproducershaveusedtheterm"tradigital"todescribecelanimationwhichmakesextensiveuseofcomputertechnology.
ExamplesoftraditionallyanimatedfeaturefilmsincludePinocchio(UnitedStates,1940),AnimalFarm(UnitedKingdom,1954),andAkira(Japan,1988).TraditionalanimatedfilmswhichwereproducedwiththeaidofcomputertechnologyincludeTheLionKing(US,1994)SentoChihironoKamikakushi(SpiritedAway)(Japan,2001),andLesTriplettesdeBelleville(France,2003).
