XBMC (Xbox Media Center)
Since 2002, the software known as XBMC has gone through three namings. First, it was called Xbox Media Player. Upon realizing that it did a bit more than your traditional media player, in 2004 the development team elected to rename it Xbox Media Center. A mere 4 years later in 2008, the team once again elected to rename the software to simply XBMC.
In 2014 the name has been changed to Kodi.
