Ed Sullivan Theater Rumor

[colortrakker]

When CBS went color, they picked Norelco cameras to avoid using anything from their arch-nemesis, RCA. The Norelco cameras lacked proper RF shielding, so had to be modified with a mu-metal coating to keep the images from going wacko. Not long after that, CBS switched Sullivan to Marconi cameras, which were much better insulated against RF. By 1973, they went back to the Norelcos.
