Line 4: '''RCA Photophone''' was the trade name given to one of four major competing technologies that emerged in the American film industry in the late 1920s for synchronizing electrically recorded audio to a motion picture image. RCA Photophone was a [[sound-on-film]], "variable-area" [[film]] [[exposure (photography)\|exposure]] system, in which the [[modulation\|modulated]] area (width) corresponded to the [[waveform]] of the [[sound\|audio]] signal. The three other major technologies were the [[Warner Brothers]] [[Vitaphone]] [[sound-on-disc]] system, as well as two "variable-density" [[sound-on-film]] systems, [[Lee De Forest]]'s [[Phonofilm]], and [[Fox Film Corporation\|Fox]]-[[Theodore Case\|Case]]'s [[Movietone sound system\|Movietone]]. When [[Joseph P. Kennedy]] and other investors merged [[Film Booking Offices of America]] (FBO) with the Albee-Keith-Orpheum theater chain and [[Radio Corporation of America]], the resulting movie studio [[RKO Radio Pictures]] used RCA Photophone as their primary sound system. In May 1929, RKO released ''[[Syncopation (1929 film)\|Syncopation]]'', the first film made in RCA Photophone. == History ==
