JavaScript was initially developed by Netscape Communications and was originally called LiveScript 1.0. Around that time, the Java language was becoming more popular and possibly as a marketing ploy, the name of LiveScript was changed to JavaScript. It was first available to the public in version 2.0 of Netscape.
