 A particularly controversial proposal, spearheaded by RCA and chairman David Sarnoff, was that the FM band needed to be shifted to higher frequencies in order to avoid this potential problem, and to make "room" for more FM radio channels.This reassignment, whose covert goal by RCA was to disrupt the successful FM network that Edwin Armstrong had established on the old band was fiercely opposed as unneeded by Armstrong, but in the end RCA's point of view prevailed.The FCC made its decision final on June 27, 1945.
