A considerable number of programs featured on Global's schedule were cancelled in the spring of 1974. By that fall, it was obvious that Global's original model was unsustainable, and it was forced to pick up a large amount of American programming to fill in the gaps. With American imports filling as much of the schedule as Canadian content rules would allow (60% Canadian overall, 50% Canadian in prime time), Global had effectively become "another CTV." With the exception of the nightly newscasts, few other Canadian-produced programs remained on the station, and the ones that did exist were largely criticized as cheaply-produced filler. John Spalding, the station's original program director, quit in 1975 after being unable to convince the station's owners to invest more money into higher-quality production.
