As the Columbia Broadcasting System expanded its

operations, soon become the largest radio network in the United 【M3】______

States, it precociously recognized the potential for the rapidly

evolved television broadcasting technology. On July 13th, 1931, 【M4】______

and ten years later began regular black and white week 【M6】______

broadcasts over its WCBW TV station in the same city, that 【M7】______

became WCBS TV in November 1946. With Television City in

Hollywood, CBS launched the industry's first full scale

production studio.

Today CBS owns television stations, radio stations, and

home video productions and distribution interests. The CBS

Broadcasting Group composed of six divisions: television 【M8】______

network, entertainment, sports, news, local television stations,

and radio.

the leader in prime time ratings, having the highest rated

shows in almost every year from the mid-1950s through the

mid-1914s. During the late 1914s, however, CBS lost its top

CBS has traditionally been strong in the TV news area. The

network began the first regular TV news program in 1948 with

Douglas Edwards as anchor. Journalism legends such as Edward

R. Murrow and Walter Cronkite gave CBS its reputation as

quality news broadcaster. 【M10】______
