NARRATOR:Listentopartofalectureinafilmstudiesclass.

MALEPROFESSOR:Nowadays,wetakesoundinfilmsforgranted—Imean,youstillmightseeblackandwhitefilmsoccasionally,butyou‘llhardlyeverseesilentfilmsanymore.Soit’sinterestingtonotethattheuseofrecordedsoundwasoriginallycontroversial.Andsomedirectors,uh,somefilmmakerseventhoughtitshouldn’tbeused.Thatitwoulddestroythepurityofcinema,somehowreversealltheprogressthathadbeenmadeintheartofcinema.Abby?

Also,thinkofthestage,thelivetheater—ithasusedwonderfulsoundeffectsforalongtime.Andifwanted,thesecouldbeproducedduringtheviewingofafilm.Youknow,therollingofdrumsforthunderorwhatever.Butthatwasn’tascommon.Oh,andanotherthing,thattheymighthaveinmovietheatersintheearlydays,wasagroupofliveactorsreadingthepartstogoalongwiththefilm.Or,andthisseemsaparticularlybadideatousnow,onepersonnarratingtheaction…anearlyexampleofalongtraditionofmovieproducers,theonesconcernedmostlyaboutmakingmoney,nothavingmuchconfidenceintheiraudience,thinkingthatpeoplesomehowcouldn’tfollowtheeventsotherwise.
