Here's one: Winning graphics no longer flashing on the screen.
Classic Concentration: When the show first aired on May 4, 1987, a champion's total winnings after the car round would display flashing on the screen. But on April 18, 1988, the total winnings would no longer be flashing when displayed on the screen.
Family Feud: Starting in 1989 on the 1988-95 version, winning Fast Money would have a winning graphic of the cash prize (depending on what version) flashing on the screen. But in 1990, the winning graphic stopped flashing and the colors: red, orange, and yellow swept through the graphic rapidly. However, originally the $5,000 graphic on the CBS daytime version would do that on special celebrity weeks only while the $10,000 graphic on the syndicated nighttime version did that regularly, but then in the spring/summer of 1991, the $5,000 graphic would do that regularly. Then in late 1991 for both versions, the winning graphics would have sparks of light run through them and they kept those graphics for the rest of that version's run, although the winning graphics returned to flashing briefly during the special Opryland episodes. When the 1999-current version first aired, the winning graphic of the cash prize would be flashing on the screen for the first 4 seasons. But starting the 5th season, the current version followed the 1988-95 version's winning graphic by having it no longer flashing and have different animations throught the season; however, the winning graphics returned to flashing briefly during John O'Hurley's final season (with brief return of the "Bullseye" game). (NOTE: The original version had a rare $10,000 winning graphic on the Friday show of "TV's All-Time Favorites" in 1983, but it wasn't flashing.)
Jeopardy!: When the current version first aired on September 10, 1984, the champion's post-Final Jeopardy! total winnings would display flashing on the screen in a Helvetica Black text. But since season 8, the total winnings would no longer be flashing when displayed on the screen.
Wheel of Fortune: Starting on October 1983 on the nighttime show, winning the bonus round would have a winning graphic of the contestant's final total winnings flashing on the screen (the daytime version didn't do that sort of thing until December 1984). Starting in January 1985, the contestant's final total winnings would be flashing on the screen regardless of the outcome of the bonus round. But, since September 30, 1996, the bonus round totals stopped flashing.
The Price Is Right: The show started having winning graphics since the double showcase bonus was installed in 1974. And these graphics would be flashing, whenever a contestant won money on the big wheel or a cash award game, the cash prize would be flashing; whenever a contestant won both showcases, the words: "Double Showcase Winner" would be flashing; or when a contestant wins his/her showcase, his/her final total would be flashing. But, since March 2009, the winning graphics stopped flashing.

And that's the first disappointment of game shows for me that I posted on this subject. I'd like it better when winning graphics are flashing, not doing various of animations. And I want any game shows in current production that used to do that to bring that back and any current game shows that has their winning graphics originally in various of animations have them be flashing too. I'm serious I want winning graphics to be flashing again.
