The Java language was initially called OAK. Originally, it had been developed for handling portable devices and set-top boxes. Oak was a huge failure. In 1995, Sun changed the name to "Java" and modified the language to require advantage of the burgeoning www (World Wide Web) development business. Later, in 2009, Oracle Corporation acquired Sun Microsystems and took ownership of three key Sun software assets: Java, MySQL, and Solaris.
