Broadcasting Corporation of America

The Broadcasting Corporation of America was a former subsidiary of AT&T.

When AT&T employees, notably Lee DeForest, developed advances in vacuum tube technologies in the 1910s, the telephone giant entered the radio business. BCA was the subsidiary formed to perform the actual broadcasting. For much of its existence, it was involved in patent disputes with RCA (then the Radio Corporation of America). AT&T decided to end this in 1926 by entering into an agreement which, among other things, transferred the assets of BCA to RCA, a development which helped advance the National Broadcasting Company to the premier place in U.S. broadcasting that it was to hold for many years.
