For many years, WXYZ-TV in Detroit was an ABC O&O station. They always carried all ABC Network programs for that reason, but there were a couple of interesting moves they made that involved the daytime schedule.
The first was in 1976. Channel 7 was airing "The 4:30 Movie" from 4:30 to 6 PM weekdays. Then they decided on expanding/renaming it "The 4:00 Movie" from 4 to 6 PM. They made some early morning local changes, and started airing ABC's "The Edge of Night," on a one-day delayed basis at 10:30 AM. In 1977, "The 4:00 Movie" aired until only 5:30 PM for more local news, and in 1982 was cut down from 4 to 5 PM for likewise reasons.
In the summer/fall of 1982, ABC News began an early morning news program, called "World News This Morining." Because Channel 7 was ABC O&O, they had to carry it, but they worked out a plan to air WNTM's first fifteen minutes, break away to air a local exercise program, and then air the last fifteen minutes of WMTM.
In 1986, WXYZ became part of Scripps Broadcasting, and thus was not always required to carry all ABC-TV programs. Because of this, WXYZ did NOT air network game shows, (including Bargain Hunters and Match Game), but did choose to air "The Home Show" and for a few years "The View," in the overnight hours. "The View," eventually began airing in its network feed slot.
