The program was later syndicated to seventy-one American television markets, expanding its viewership beyond its primary New England viewer base.

The program has no relation to the current group of local morning shows produced by the Fox owned-and-operated television stations, all of which use the Good Day title.

WCVB-TV, which had signed on the air one year before the premiere of Good Morning!, developed the show as a part of their effort to produce more local programming than any other network affiliate in the country.

Bruce Marson, who had produced the first season of WGBH-TV's successful children's series Zoom, was hired by WCVB management to launch the new 90-minute live morning variety program they were creating.

In the mid-to-late 1980s, the in-studio set came to resemble more of a giant, elegant-looking open foyer, with a kitchen island moved into the center for the cooking segments.

also broke ground by taking its entire production on the road and broadcasting from locations outside of the Boston area and around the world—a feat of which was considered exceptional for a locally produced program.

Prose, a former 1966 Miss America contestant, was a multi-talented television personality who brought her skills as a host, interviewer and singer to Good Day!.

Coinciding with Langhart's return, the program adopted the modified title of The Good Day Show, which lasted during the 1980–81 season.

Langhart left the show again at the close of that season when she was hired to be a field correspondent on the 1981 syndicated weekday revival of You Asked for It.

Langhart, whose Boston TV exposure had most recently been as a reporter/news contributor on CBS affiliate WNEV-TV (present-day WHDH), returned to Good Day!

[15] For several months following Langhart's departure, Cottle remained a co-host with Prose; by the start of 1988, he was relieved of hosting duties and was strictly a contributor thereafter.

Ted Reinstein, longtime co-host/correspondent of WCVB's nightly newsmagazine Chronicle, was a correspondent and substitute host for Good Day!

after 18 years, due to New England's then-current economic downturn putting severe constraints on the local broadcast stations.

followed a wave of other locally produced programs coming to an end in the Boston market within that same year, also due to a lack of financial viability in a struggling economy; among them were WBZ-TV's Evening Magazine, WHDH-TV's Ready to Go and Our Times, WGBH-TV's The Ten O'Clock News, and a host of others.

was announced, WCVB's management offered Eileen Prose the hosting role on a new weekly Sunday morning lifestyle/discussion program.

set, and like the long-running weekday morning series, it featured Prose interviewing and having discussions with experts in various fields, ranging from economics and politics to sports and entertainment.

Also as on Good Day!, Frank Avruch was a regular contributor and segment host, often discussing new happenings in entertainment and interviewing guests as well.

Prose was immediately succeeded as host by Susan Wornick, who was then WCVB's weekday afternoon news anchor and investigative reporter.
