MrBeast was just on Flagrant with Andrew Schulz for 4 hours, a day or so ago: https://www.youtube.com/watch?v=WGrk7Mzm4uo
This was also an interesting and fun interview which I expected to skip over fairly quickly but ended up listening to in the entirety. Some discussion over how you would lose something like 3% of viewers if somebody sneezed, went to the toilet, and so on.. Other things to avoid, like any signalling that the video is winding down will lose you a huge chunk of viewers instantly.
I watch woodworking youtubers and a couple of them had a behind the scenes discussion about their channels and also came to the conclusion that any wind-down loses viewers and this affects a channel. The algorithms use metrics of how long someone watches so it makes sense to end abruptly rather than have 30-60s of wind down.
Mr Beast's team must have second by second analytics on every video to know what works, what doesn't for the types of videos they produce.
The reason YT doesn’t want show to wind down is because it provides people with a nice and natural place to stop watching which is nice. The race towards shorter, easier, more catchy and relentless content is a race to the bottom making everyone dumber.
Watching TikTok for an hour is probably the most depressing experience I ever had when it comes to my general opinion of humanity. Yet I’m here commenting and I’m not convinced that it is a better use of my time than TikTok. Sometimes I wonder if what the internet has actually done to us was worth it.
It's a little muddy.
On the other hand, think about what benefits the platform. Executing a sudden ending that leaves people engaged and ready to continue to watch, rather than a friendly sign-off that gives people permission to go about their day like a healthy human being?
YouTube inherently will be strongly motivated to keep people connected and watching, rather than happy or healthy. So it's got me wondering about sign-offs that might invoke this reality. I'll have other videos, the viewer is not guaranteed to go from mine to a MrBeast video. If I wanted to be cagey about it I could try to connect to another video of mine: I've seen this done by others.
It makes sense if you assume that YouTube will reward you for keeping the viewer from switching off, through and beyond the end of your video. You become complicit in an attention engine, with some known parameters: you are there to keep people watching. What you do isn't relevant. You could be helping or hurting them, whatever you like, so long as you keep people on YouTube, and whatever YouTube does for metrics or algorithms, you can be sure that keeping people tuned in is an existential need of theirs and you'll always be rewarded for directing people to more YouTube. of ANY kind. Doesn't have to be the latest MrBeast. If you can successfully direct people to any other video of your choice, yours or otherwise, that still counts.
It doesn't fully match your requirements but Mr. Beast was on Joe Rogan a few months ago. A fantastic interview and they talk a lot about the stuff you mention (voice actors, hiring people, etc.)
I see a guy that basically operates like a game show host but also does things like TeamSeas, cleaning 30 million pounds of trash out of seas/oceans.
From watching a couple of interviews, things I've picked up - when his youtube videos were grossing $20-30k a month he started hiring people and said he hires about 1 person per month since then. He has a teams of accountants, editors, producers, etc. He decided early on to have videos translated but would hire premier voice actors in countries, like someone that voice acted Batman to do his voice. He has an obsessed culture of making the best videos. He built a huge studio and lives there.
I see many similarities to what I've read about startup founders and a growth mindset. If anything, there are some huge marketing lessons to be learned from how he runs his business. I would love to see an experienced interviewer with knowledge of the business world/startups interview him.
