Blizzard's game launcher (use to?) downloads the games via Torrent. E.g. starcraft II, world of war craft, etc. That's pretty damn mainstream. A lot of older networked games were, probably some modern ones too. One player hosts the game (either picked automatically by the match making system, or by running a game server listed by a index server), and everyone else connects to them. Call of duty, counter strike, starcraft, etc. As other people mentioned the internet, also texting and telephones, but the peers in this example are really big. I think some of the bank transfer stuff is also a "distributed" system with big peers. FireChat (distributed chat over wifi) was reasonably mainstream in Hong Kong for awhile: https://www.cbc.ca/news/science/firechat-off-the-grid-messaging-app-what-you-need-to-know-1.2784271 https://www.cbc.ca/news/science/firechat-off-the-grid-messag...
