WNBT (later WNBC) schedule for first week of commercial TV programming in the United States, July 1941

The first regularly scheduled television service in the United States began on July 2, 1928. 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.^[81][82]

Hugo Gernsback's New York City radio station began a regular, if limited, schedule oflive television broadcasts on August 14, 1928, using 48-line images. Working with only one transmitter, the station alternated radio broadcasts with silent television images of the station's call sign, faces in motion, and wind-up toys in motion.^[83][84]Speaking later that month, Gernsback downplayed the broadcasts, intended for amateur experimenters. "In six months we may have television for the public, but so far we have not got it."^[85] Gernsback also published Television, the world's first magazine about the medium.

General Electric's experimental station in Schenectady, New York, on the air sporadically since January 13, 1928, was able to broadcast reflected-light, 48-line images via shortwave as far as Los Angeles, and by September was making four television broadcasts weekly. It is considered to be the direct predecessor of current television station WRGB. The Queen's Messenger, a one-act play broadcast on September 11, 1928, was the world's first live drama on television.^[86]

Radio giant RCA began daily experimental television broadcasts in New York City in March 1929 over station W2XBS, the predecessor of current television station WNBC. The 60-line transmissions consisted of pictures, signs, and views of persons
