Blizzard is this celebrating their 20th anniversary, they released a timeline on their website where you can check out all of their companys, games, and additions (such as the great battle.net merge)
I really recommend you go check out the website, as its really cool and might show some of their projects that you didn't knew of.Twenty years is a long time, and much has happened since we first opened our doors. We invite you to check out our new timeline detailing the 20-year history of Blizzard Entertainment and join us as we take a stroll down memory lane
