Grimy Chorizo cried when Colbert signed off? Colbert lost his show when his shrinking viewership intersected with consequent ad revenue shrinkage intersected. CBS realized that the two shrinkages meant that the prestige they got from having a big-name headliner had shrunk, making the $$$$ losses not worthwhile.
President Trump's first election in 2016 absolutely broke his brain. He was in last place in late-night, then turned his "entertainment" venture into an unfunny group therapy session for TDS addled lib-turds.
I did not cry when Carson and Leno retired. They retired when they were still going strong. The one thing about Leno that does "get to me" is his loving and faithful for Mavis, who is going through dementia. That is class and beyond, pretty much heresy in Hollyweird.
I don't cry either when a TV show ends. I'll reminisce about it how much entertainment value it brought to me. That's why I love sports (although some are lessening these days). In a sporting event, there is a game or season where one can devote themselves to "their" team and celebrate and agonize constantly. But there is always a winner and loser, and sometimes you're the windshield, other times you're the bug.
Carson reruns are still available and still funny, simply because he didn't take himself seriously as Coal-bert and the Jimmy's do. Leno was largely the same way, as was Letterman until something broke his brain. For many of these clowns, marrying a left-tard easily accomplishes that. Kimmel used to be funny on Fox NFL pre-game, The Man Show, Crank Yankers, and then left his "normal" wife for a woke-tard Kimmel Show writer who neutered both his testicles and his sense of humor.
As you likely know, I'm a Gutfeld fan, and know exactly what I'm getting with him. A short batch of jokes poking fun mostly at lefties and The View, an often politically tinged amusing monologue, and then five segments which might or might not have nothing to do with politics. He surrounds himself with less than 10% of a staff of the major legacy networks and gets better ratings albeit being on something like 50 million less homes.
