Roblox was first released in 2004 under the moniker DynaBlocks. The name's authors, David Baszucki and Erik Cassel, thought it would be difficult to remember at the time, especially given the target demographic's younger age range. As a result, they chose to call it Roblox in the same year, and it has remained that way ever since. Surprisingly, the game was also known as Roblox v ten at the time.
