What was the last television series originating from the Dumont Television Network to air new episodes? (This might be a program that switched from Dumont to another network.)

DuMont also aired the first TV situation comedy, Mary Kay and Johnny, as well as the first network-televised soap opera, Faraway Hill. Cavalcade of Stars, a variety show hosted by Jackie Gleason, was the birthplace of The Honeymooners (Gleason took his variety show to CBS in 1952, but filmed the "Classic 39" Honeymooners episodes at DuMont's Adelphi Theater studio in 1955-56).
