Founding Story
Ralph J. Roberts ran Pioneer Industries, a men's belt and accessories business, before looking for a new industry in the early 1960s. With partners Daniel Aaron and Julian Brodsky he bought a community antenna television (CATV) system in Tupelo, Mississippi in 1963 for about $500,000, serving roughly 1,200 subscribers. The company, first called American Cable Systems, was renamed Comcast in 1969, a blend of 'communications' and 'broadcast', and went public in 1972.

Ralph J. Roberts
Ralph J. Roberts co-founded Comcast in 1963 when he and partners Daniel Aaron and Julian Brodsky bought a cable system serving about 1,200 subscribers in Tupelo, Mississippi for roughly $500,000.

Daniel Aaron was born in 1926.
Julian Brodsky
Julian Brodsky co-founded Comcast in 1963 and served for many years as its chief financial officer and later vice chairman. A trained accountant, he arranged the debt financing that let Comcast buy cable systems using their predictable subscription cash flows, funding expansion through the 1970s and 1980s.
