For context, battle.net the service has existed since 1996. Back in the day it was just used for the multiplayer component of games like Diablo and Warcraft. I think it's still meaningful to point this out because even if it wasn't a launcher like it is today, it was still a social media/communications platform which is a meaningful part of why people use certain launcher platforms/stores.
Yep! In fact, a few years ago Blizzard tried to sunset the Battle.net brand and rename the launcher to just Blizzard Launcher or something, and they eventually gave up on that because the community was really attached to the Battle.net name. For many gamers Battle.net was one of the first online experiences.
Of course, battle.net 1.0 wasn't continuous with battle.net 2.0 which launched with starcraft and eventually subsumed wow and d3 accounts. If you had some account on battle.net for brood war, it died with the move to remastered.
