Chris' YouTube page does have 76 episodes from Season 1 (EP1) through Season 4 (EP18). With a bit of searching on YouTube you can find other Season 4 and Season 5 episodes on YouTube. These later episodes are more easily located on his Patreon Page and as they are YouTube content, you can still play them from there rather than search them on YouTube without being a donor. But honestly, at $2 a month he needs to be supported given how much he supports the community. At $10/month you start to get the scene files. Something to consider if you feel like you are missing out on cool scene assets only available through Maxon One (though they will NOT be the same assets).
Chris is an amazing educator. The fact that there is still so much of Chris's content on YouTube is pretty amazing.
His "What's New in RXXX" are a staple to the entire community. Just amazing how much content he can pack into those in such a clear and concise way. We've just come to expect his video to be immediately available within hours of each C4D release which (I am sure) puts a lot of pressure on Chris to create it. We should not take for granted all the work he puts into them. The 4-hour session on 2024.4 was pure gold.

As an aside: There is a simple trick to see how much your content means to the community: Change people's expectations and don't produce the "What's New" videos like clockwork and wait for the reaction. If "What's new in R2025" did not come out within 2 weeks of R2025's release, there would definitely be a huge buzz about what if anything happened (IMHO). From people asking questions in the forums to checking the obituaries and local area hospitals. I honestly believe there would be that level of concern. (BTW: Same goes for EJ as well).
