It's not what it once was, but they're still the same two blokes they've always been. Only now they're in their 40s and have a lifetime of accumulated experience, wealth and contacts to back them up.
Sponsors seem to throw themselves at MCM. Though the way MCM's sponsorships seem to work are more in the way of old-school product placement in TV and movies. That's why many episodes have a 5 second shot of Castrol products being poured into an engine and why a random Ranger or Transit turns up whenever they need to lug some shit around.
At least they're self-aware enough to not set up a Patreon. Seems like the merch, the sponsorships and the ad revenue is enough to keep growing the channel.
What I admire more about the MCM guys is that they're so private. They're not constantly hunting for self-promotion and they're not tweeting out every brain fart they have. Marty and Moog are anti-cows.
That's just Moog flexing his mad music production skills. The musical numbers have been part of MCM since the early days.
Apparently MCM has been approached on more than one occasion to make TV shows for major networks, but they've turned these offers because they're worried about losing creative control. I think these guys are Wayne's World fans.
That said, apparently they did a deal with Discovery to make some clip shows of existing MCM stuff. I haven't had cable TV for at least 15 years so I couldn't tell you what these are like.
Oddly enough, I think Hoovie's Garage is more contrived than MCM. Hoovie isn't anywhere nearly as dumb as he lets on (though he's probably almost as much of a goober irl as he comes across in his videos). As for the other two... yeah, I don't watch Matt's Off-Road Recovery and I kinda dip in and out of Tavarish's videos. I didn't mind the first few seasons of Car Trek, but that's feeling way too formulaic now.
