I imagine a lot of people who are into data hoarding already know a lot of this but I thought the video was pretty neat. It briefly talks about the history of different compression formats and provides a brief blurb about why you may want to use one or the other.

I’d recommend checking it out if you want 15 minutes of background noise.

For anyone new to data compression TechQuickie and CrashCourse have videos on it. If you really want to go down the rabbit hole you could check out media compression and see how things like JPEGs and PNGs work.
