Some that might interest folks here:
- Real Player - The inventors of streaming & the poster child for enshittification
- iRiver - perhaps the first major MP3 (and OGG!) player. DRM & iTunes not required.
- Napster - P2P for the early adopters
- KaZaA, Limewire & Bearshare - P2P for the masses. (And BTW the source of my user name: klu9 = KaZaA Lite User 9)
- MP3.com - At first indie artists uploading their own materials, then users uploading their own CDs
- Radio.Blog.Club - Embed an MP3 in your blog
- Grooveshark - Streaming all music
- Usenet - A shadow of its former self but still a bastion of binaries
Personally, got started with Audiogalaxy, went all in with Morpheus & KaZaA Lite. Loved Grooveshark, discovered so much there. Still have a few RMVB (Real Media Variable Bitrate) videos burned on DVD-Rs somewhere.



To get started, I’d say to get a cheap block account from the Reddit Usenet deals wiki: https://www.reddit.com/r/usenet/wiki/providerdeals/. A block account gives you a fixed amount of download (1TB, 2TB, whatever) that lasts indefinitely. If you use it just for music or books (for example), one block could last you a very long time. If you find yourself needing more data, you can get a monthly subscription with unlimited data.
You also need an indexer, which is how you search for content. DrunkenSlug, NZBGeek, and NZBPlanet are popular. These cost money, but sometimes they have a lifetime plan where you just pay once. Sometimes they have open registration, but other times you need to get an invite from an existing user. There’s free indexers like NZBKing, but they’re often full of junk, and lack encrypted content.
SABnzbd is the most popular downloader software. It’s free and open-source.
I think that’s it for the basics. There’s more to it - different backbones have different data so one provider might have data that a different provider is missing , you can fully automate downloads with Lidarr/Radarr/Sonarr/Readarr, you can aggregate results from multiple indexers using NZBHydra/Prowlarr - but you can figure that out as you go :)
