This is exactly what I feel I've been driven to this last year. I don't want to have all my media spread around on a tenfold different streaming providers, nor do I want to live with the random removals of offerings that seem to happening more and more where I live.
The day I have children I want to be able to share some sort of cultural archive with them, though regular tv might probably be dead by that time, who knows.
I've started hosting my own plex server, and using torrents and actual old backups to get the content. The sad part though, is that most of the major torrent sites seem really dead compared to the haydays. What are some good options these days?
It had hard-to-find shows, and it kept track of who downloaded what, so if there were no active seeders, you could ping some people to seed it so they could earn credits.
Fair warning - these sites have some of the obnoxious browser hijacking javascript I have ever seen (and they keep upping the ante every few months) but updating your hosts file to block the ads helps a bit - rarbg and ettv complement what is available on each other and tpb.
