On returning to Kansas City, Storck rejoined WDAF and again resumed newscaster duties but soon moved on to become campaign manager of Kansas City attorney Jerome Walsh's unsuccessful run for congressional office. Storck then joined the staff of T. R. Finn & Associates as its publicity director. He was assistant director of education and organization for the Consumers Cooperative Association, now known as Farmland Industries, from 1947 to 1949 and was public relations director and assistant manager of the North Kansas City Development Company in 1949 and 1950. He was also a semi-professional actor in local radio, television, civic theater, and in films made in the Kansas City area. Storck's first wife, the former Barbara Marsh, died of bulbar polio in 1950. He later established a Barbara Storck Memorial award for poetry at the University of Kansas City in her memory.

Shortly after his wife's death, Storck returned to broadcasting in 1951 and joined the staff of Kansas City's first television station, WDAF-TV (Channel 4), becoming the region's first television weather presenter. Within months, he played an instrumental role in the station's coverage of the Great Flood of 1951. Despite his local popularity, Storck left the WDAF-TV post after a labor dispute in 1953.

Shelby Storck continued in radio and television work through the 1950s, working between Kansas City and St. Louis, making documentary films which he often narrated as well as produced. He frequently acted in industrial and educational films produced by the Calvin Company of Kansas City and by the Centron Corporation of Lawrence, Kansas. There, he worked with such notable directors as Robert Altman and Herk Harvey. In 1954 he became general manager of KETC in St. Louis, a newly founded educational television station.

From 1955 to 1966 Storck was associated with Charles Guggenheim of St. Louis as a director and narrator of documentary and commercial movies produced by Guggenheim. Among the films Storck made while associated with Guggenheim were several award-winning documentaries on St. Louis history. Storck remarried, to longtime friend Jacqueline Field, in 1956. In 1960 the Storcks moved from Kansas City to St. Louis. In 1966, when Charles Guggenheim transferred his operations to Washington, D.C., Storck formed his own production company in St. Louis, Shelby Storck & Associates, Inc., and began producing documentaries and commercials. He was best known for making half-hour campaign biographies for politicians, mostly under the direction of media consultant Joe Napolitan, including successful films for Milton Shapp, Winthrop Rockefeller, and Mike Gravel. In 1968 Storck wrote, produced, and directed a half-hour promotional documentary on Hubert Humphrey called What Manner of Man, which was hugely instrumental in Humphrey's sudden surge in the polls towards the end of his unsuccessful race against Richard Nixon for President of the United States.

Shelby Storck had been diagnosed with heart disease and was under a doctor's care for several months. He died in his sleep, apparently after a heart attack, at home in St. Louis in April 1969. His wife, Jackie, was on the way by air to Taiwan to visit a sister when he died, and funeral arrangements had to be delayed for several days until she could return to St. Louis.

There currently exists a Shelby Storck Award for Excellence in Undergraduate Teaching at the University of Missouri-Kansas City. The annual Storck Awards for Notable Achievement in the Political Advertising Arts were established by the Washington Post in 1980. Today, Shelby Storck is primarily known for the political films he produced in the 1960s, as well as for his role as a hard-nosed, wise-to-the-world police detective in the 1958 Kansas City-produced feature-length film The Cool and the Crazy (where his wife Jackie also makes a cameo appearance).

Shelby Storck had three children: Shelby Randall Storck (1943–1987), who followed in his father's journalistic footsteps and became a photographer; Phillip Alan Storck (b. 1944); and Gael Winslow Storck (b. 1950). He also had a stepdaughter, Kathy Field (b. 1948) from his second marriage.
