Magic: The Gathering, after becoming one of the most well-known TCGs ever to be made, would lead to many nasty trends with not only MTG itself, but with other card games in general. The first being that packs would lead to the loot box trend that would later be seen in video games, and the whole obsession about MTG cards being an investment, which is why the whole debate about the Reserved List exists. (which is Wizards of the Coast's statement that says that certain older cards will never be reprinted again, to ensure their value) In addition, WotC has been going all-in on trying to raise their ESG score, using every imaginable tactic available, i.e. blackwashing characters on cards, troon players and casters for MTG events, and the cancellations of Terese Nielsen and Seb McKinnon, because of their political beliefs. Also, WotC (along its parent company Hasbro) has been getting more and more aggressive with power creep, and pushing out product after product, purely to milk the shit out of whales, such as the various Secret Lair sets, including crossover collaborations such as with Fortnite (Yes, that is a thing), Hasbro's other IPs (i.e. MLP, Transformers), and Street Fighter. The whole 30th Anniversary Edition, where are selling proxy cards of Beta Edition (as in they are not even tournament legal), at a price of
$1000 for 4 packs, threw out any form of subtlety in regards to WotC and Hasbro treating MTG as a cash cow.
The whole TCG deal also lead to other various TCGs coming out, to varying success. Some successful ones included Yu-Gi-Oh!, and Pokémon's TCG, which Wizards of the Coast was actually in charge of designing the English cards, until the license was transferred over to The Pokémon Company in 2003.
Also, Pro Wrestling promotions, i.e.
World Wrestling Federation/Entertainment,
World Championship Wrestling,
All Elite Wrestling, would also lead to nasty trends with both the fanbases of them, and the promotions themselves. You have the whole carnie shit that goes on behind the scenes of those promotions, and the fanbases of them are on their own levels of toxic. I don't have that much knowledge about the deep behind-the-scenes stuff with that, would anyone that knows more about it give some examples?
Michael Bay's The Rock and Roland Emmerich's Independence Day ushered in a new era of summer blockbusters that were dumber, louder and more in your face.
Taken on their own The Rock and Independence Day are good movies and their bombastic style is appealing, but they killed the good momentum summer blockbusters had been on from 1977-1993, when everyone tried to imitate Emmerich and Bay instead of Spielberg and Lucas things got way, way dumber and more obnoxious and Bay and Emmerich themselves proceeded to make nothing but crap after those two movies.
Titanic ruined James Cameron, something bad went to his head and all we've gotten since are blue space cat people movies instead of cool shit like Aliens, Terminator 2 and True Lies.
Also, Roland Emmerich's 2012 was the final nail in the coffin in regards to disaster movies, since there were so many (I think?) that the genre was getting stale and people were getting tired of them. Sure, there were later films like Sharknado, but the disaster movie genre hasn't got back to the levels that movies such as 2012 and The Day After Tomorrow did.
