From Flint, Joseph moved on to program WMAX in Grand Rapids and WKBW in Buffalo (which he later described as his first prototype of the Hot Hits format), and then in 1960, he helped transform WABC in New York City from a struggling, cash-strapped block-programmed outlet into one of the dominant Top 40 stations in North America. In the fall of 1963, following another success story in Grand Rapids at WLAV, Joseph oversaw the transformation of struggling MOR station WKMH in Detroit into WKNR (Keener 13), still fondly remembered as one of the Motor City's most popular radio stations ever, and a few years later oversaw a similar turnabout at WFIL in Philadelphia. His resume also included stations in Minneapolis, St. Louis, New Orleans, Puerto Rico, and other markets, in a variety of formats from Top 40 to talk radio to beautiful music (Joseph admitted to being a classical music aficionado in a 1983 "Billboard" magazine article).
