In 1929, Terry left his producer, Amadee J. Van Beuren to open his own studio, with distribution covered by Educational Pictures. The farmer was again revived and made frequent appearances in the earliest Terry sound shorts. But as Terry's studio began to grow and develop, Farmer Al Falfa wore out his welcome and was subsequently all but retired. The Farmer never entirely disappeared, though; he was featured as a supporting player in the first two Heckle and Jeckle cartoons, released in 1946, and starred in Uranium Blues (1956) ten years later.
In the fall of 1958, the white-bearded protagonist starred in the syndicated television program Farmer Al Falfa and his Terrytoon Pals, a compilation of the earlier black and white Terry shorts. Though no longer for sale in the mainstream television market, most of the early cartoons, the silents in particular, have surfaced on public domain compilations including, most notably, Video Yesteryear's Cartoonal Knowledge VHS series from the 1980s.
In the early 1950s, the character was unofficially rechristened "Farmer Gray," probably by Fred Sayles, the host of a children's program called Junior Frolics on station WATV in Newark, N.J. Sayles certainly named some of the subsidiary characters (presumably previously nameless), e.g., "Bumpy" the donkey, "Casper" and "Bad Mike," the cats and "Marty" and "Millie," the mice.
In mid-1950s Terrytoons comics, the character was also briefly rechristened "Farmer Gray", presumably in an effort to capitalize on "Junior Frolics". But the renaming in comics didn't last—it was done inconsistently (sometimes changing from month to month), and by the late 1950s, the character's original name was back permanently.
