Kodi, or XBMC, is flexible open-source software for streaming media players. It has dozens of add-ons for playing video from lots of places on the Internet, right on your TV. At the fair today, I saw a couple shady vendors selling little Android boxes with Kodi for hundreds of dollars. If you really want to save money, just buy a cheap Amazon Fire TV stick and do it yourself. It’s not that hard.
