Mark's Accidentally Obsessed
One random interest. Full-blown rabbit hole. Forgotten formats, weird tech, pop-culture what-ifs, creator stories, and whatever hijacks the week next. I learn it, overdo it, and bring you along.
The vibe
Rabbit holes. Hobbies. Hyperfixations.
New obsession loading. Come for the deep dive, stay because you now also want a MiniDisc deck, a LaserDisc player, and a suspicious stack of obsolete media.

About
Welcome to the hole
Mark’s Accidentally Obsessed is the channel where one random interest turns into a full-blown obsession. YouTube is the main stage. TikTok is the side quest — I post there semi-frequently, but the long-form rabbit holes live on YouTube.
