when was the television introduced to the public
History of television P>The first regularly scheduled television service in the United States began on July 2, 1928, fifteen months before the United Kingdom. The Federal Radio Commission authorized C. F. Jenkins to broadcast from experimental station W3XK in Wheaton Maryland, a suburb of Washington, D.C. For at least the first eighteen months, 48-line silhouette images from motion picture film were broadcast, although beginning in the summer of 1929 he occasionally broadcast in halftones.[149][150]
The Wizard of Oz on television From the beginning The Wizard of Oz was telecast in color, although few people owned color television sets in 1956. Except for 1961, all U.S. telecasts have been in color, an effect that seemed much more striking in the early 1960s, when there were still relatively few color programs on television. It was not televised in color in 1961 because color telecasts had to be paid for by their sponsors, who declined to do so that year.[15][16] Between 1956 and 1965, the Wizard of Oz showings were rare exceptions to the black and white program schedule at CBS. During this period, CBS had the ability to broadcast programs in color, but generally chose not to do so unless a sponsor paid for a film or program to be shown in color. During this period, the competing network NBC was owned by RCA, which by 1960 manufactured 95% of the color sets sold in the U.S. Hence, CBS perceived that increased use of color broadcasting would primarily benefit its rival by promoting sales of RCA color television sets.
