Television debut (1948–1954) The television debut came on January 18, 1948 on the DuMont Television Network with Mack as the host. The regular staff for the television show included Lou Goldberg (aka Lewis Graham); Lloyd Marx, musical director; accompanist Dotty Marx, his wife; Jack Hoins, writer/producer; and Marguerite (Dwyer) Scheid, talent scout. The show regularly traveled to other cities across the United States and made at least two trips to Europe for the USO. In the early 1950s, the show went to Washington, D.C., for a memorable benefit featuring contestants from the United States Congress and the Truman administration. The series is one of only six shows—the others were The Arthur Murray Party; Down You Go; The Ernie Kovacs Show; Pantomime Quiz; and Tom Corbett, Space Cadet—to appear on all four TV networks during the Golden Age of Television. The series was broadcast weekly, on early Sunday evenings, on DuMont until September 25, 1949, then moved to NBC Television in October 1949 where it remained until September 1952. NBC then hosted it from April 1953 to September 1954. The Original Amateur Hour finished at #27 in the Nielsen ratings for the 1950–1951 season.

It then ran from May 1959 to October 1959 on CBS, before returning to ABC for a last prime-time run from March 1960 to September 26, 1960. Even then the show wasn't finished—it ran for another decade as a late-Sunday-afternoon feature on CBS, beginning on October 2, 1960. Many long-running CBS shows were canceled in 1970–71 because they attracted viewers of an advanced age. Mack's show was among the first to go, though not as a direct result of the other cancellations. Its Sunday afternoon timeslot was subsumed by the NFL on CBS at the start of the 1970 season as a result of the AFL–NFL merger and its expanded game slate, with CBS beginning to carry football doubleheaders. The network announced the show's cancellation on November 2, as Geritol dropped its sponsorship of the series, one of the last vestiges of the Golden Age where single-series sponsors
