"The ones that I can think of would be "Bruce Almighty" with Jim Carrey who was the "weekend anchor" at WKBW Channel 7 in Buffalo. They used the actual calls and "Circle 7" logo. "
The film not only borrowed the callsign, logo and location of WKBW-TV, but a lot of character and plot points from that station's history from the late 1970s to the late 1990s, all of which Carrey would have known and probably contributed to the development of the story and script. Jim Carrey's character is modeled on real-life former Channel 7 feature reporter Don Polec, who's been at ABC O&O WPVI in Philadelphia since the early 1980s (but would have been a part of Carrey's teenage memories since Channel 7 was arguably the most-watched station in Southern Ontario when he was growing up in the late 1970s). The central plot point of the Carrey character's frustrated desire to take over as chief anchor for a retiring icon was inspired by the real-life 1998 retirement of longtime Channel 7 anchor/news director Irv Weinstein, who'd been the legendary face and voice of that station's news for 40 years.
Got to know some of these people while working at channel 7's then-sister station WKBW-AM 1520 years ago...so the whole thing had a ring of familiarity, not to mention more than a few inside jokes veterans of the Buffalo radio/TV wars probably got.
Another sidebar...if you watch WKRP in Cincinnati, you'll see some jokes and plotlines, like the episode about the busted "guess the 10 song snippets" promotional contest, inspired by real life events at WKBW. Ex-KB overnight jock Casey Piotrowski was a writer on the show, and he borrowed from his years at KB. That contest fiasco actually happened at KB and was a favorite story among station old-timers long before it got into a sitcom script. And the winner of that busted contest? His name was borrowed from the real name of popular longtime Buffalo radio personality (former KB jock, now WBEN talk show host) Sandy Beach.
