because guys that develop decided to change XBMC name to Kody, because of name usage problems. Xbmc was originally developed as Xbox Media Center and Microsoft was putting pressure on them to change the name.
Anyway as you can read on http://www.tvaddons.ag/
Xbmc or Kody is the future of television, very extensible media center system.
If you run on problem with setting up or installing you can ask in Xbmc Google+ community or on forums on http://forums.tvaddons.ag/
