With how much media is produced, not all of it can get the proper documentation it deserves. Lost media is a term that represents those pieces of media that have fallen into obscurity. Whether it be an episode of a cartoon, a piece of music, or even a website, one of your favorite pieces of media might be undocumented, let's talk about it!

In this video, we'll be going over some of the most fascinating examples of this phenomenon, ranging from an unlicensed SpongeBob documentary, unreleased cartoon reboots, forgotten pieces of music, extremely rare merchandise and much more.

Update April 2022: The start of the "Most Mysterious Song on the Internet" segment received a copyright claim, so it had to be trimmed about 30 seconds. Unfortunately, we lost a Quagmire appearance. Kinda funny a video about lost media now has a semi-lost section.
