For me, it's the seldom remembered gaming TV show PXG for the children's network Jetix.
Back in 2004, alongside a push for corporate alignment as Disney had bought the then established Fox Kids to then rebrand into the action-adventure brand Jetix, Jetix in the UK commissioned a little known show called PXG from the production company Prism Entertainment, whose staff previously worked on other gaming TV shows like Gamezville for Sky One and Lan Jam for CITV.
Unfortunately, because this show was relatively new and at this point, DVRs like Sky+ became more prevalent, Jetix hardly reran the show on it's schedules, and I know this cause I've checked many TRILT pages (TRILT is essentially an in-depth archive of schedules, most universities in the UK have access to it) to find PXG hardly mentioned nor really kept archived due to it.
Is the show good? Ehhhh, not really. It's pretty much a show you wouldn't be able to get away with now, especially with the stereotype of the host, Kentaro, but it's a good look if you're into the ways that TV tried to present gaming as a complement to TV, and it made sense for a channel like Jetix to have a show about it.
I have helped with the production of certain videos about the show, but one of them is from a guy who I fucking detest and wish him a very "career end" because he is such an arrogant prick. Besides that though, there's plenty of information about the show on the Lost Media Wiki, and I'm always on the eye out for any new found PXG media.
