I used to watch various cartoons made my Mondo Media years ago like Dick Figures, Gundar, and Deep Space 69, but I haven't watched either consistently in a long while. I did recently re-watch a couple old and new Dick Figures though (including a "Chick Figures" cartoon from a year ago, and for those that don't know "Chick Figures" is an official Rule 63 spin-off that started as a joke but it became popular enough to gain more episodes outside of the original joke one) and sure a couple jokes might seem aged now (mainly any episodes that involve "Trollzor," a parody of stereotypical internet commentators who unironically enjoy rage face comics, and his facial expressions are always represented with said rage faces), but I dunno why I just "dropped off" any of those aforementioned series (weirdly one thing I forgot is I actually knew of Danny Sexbang before Game Grumps because of a thing he did with Mondo prior to Grumps where he helped promote some new shows Mondo introduced this one particular summer years ago).
Also when I was new to lets plays I used to watch a lot of Pewdiepie, but now I barely watch him. I know Markiplier and Jacksepticeye are similar commentators and all three of them like to joke about how they're basically clones of one another, but I kinda found Mark and Jack more enjoyable than Pewds overall. I did check out some of Pewds more recent stuff as I heard much of his 2016 output has actually been non-gaming related and he's kinda taken on a slight Filthy Frank influence now (also he made a video rather recently where he admits he finds a lot of his older material very cringe inducing), and some of it is rather enjoyable to be honest.
