(Jewish website bragging about media control)
"Only NBC, CBS and ABC remained until the 1980s when cable and satellite, facilitated the creation of CNN, Fox, Warner, and others. Of the three original networks, all three had Jewish roots."
"
Columbia Broadcasting System (CBS): Arthur Judson, a leading talent agent, was miffed that David Sarnoff had failed to include any of his stars among the NBC roster. In 1927, with help from the Levy brothers of Philadelphia, Judson founded the Columbia Phonograph Broadcasting System. Within a year of its first broadcast, the Company was nearly bankrupt with only sixteen affiliate radio stations. Judson sold out to Jerome Loucheim, Ike, and Leon Levy (who was engaged William Paley's sister.) Paley was the son of Ukranian Jewish immigrants and a second generation cigar maker.
Twenty seven years old, Paley discovered radio advertising helped him sell cigars and he was sufficiently well off that in January 1929, he bought majority control for $400,000 and renamed it the Columbia Broadcasting System. Through the '30s, Paley expanded CBS. He pioneered the offer of free programming to affiliate stations in exchange for an option to sell advertising, which he sold in huge chunks. He had an unerring eye for talent, signing up Bing Crosby, Kate Smith, Lucille Ball, and Ed Sullivan. He also showed his survival skills by cutting a depression era deal with Abraham Zukor of Paramount. It helped keep Columbia afloat through the tough times.
From 1955 on, Paley's talent and instincts for popular programming such as "I Love Lucy," and "The Ed Sullivan Show" made CBS the ratings leader for twenty one years.
Paley also pioneered first rate news coverage encouraging the reporting of Edward R. Murrow and historian William Shire during World War II. They, in turn, fathered a generation of excellent successors including: Eric Sevaried, Howard K. Smith, and later, Walter Cronkite.
Despite the failure of the innovative CBS approach to color television, the same CBS inventor, Peter Goldmark, next created the long playing 33 rpm record. It helped make CBS Records America's leading record company.
Until non-Jew Ted Turner arrived on the scene in 1986 and threatened a takeover, CBS was Paley's fiefdom. Responding to Turner's takeover attempt, Paley turned over control to Lawrence Tisch who had purchased 25 percent of CBS's stock. Tisch ran CBS until 1995 when Westinghouse bought it. A few years later, in a deal that brought Paramount and CBS back together as siblings, Sumner Redstone's Viacom, took over CBS. For a time, Viacom's Mel Karmazin served as President. As such, CBS has remained under Jewish management in one form or another for nearly its entire existence. "
