content: Kodi boxes are small enclosures that house htpcs (home theater pc) built for the HTPC software called "Kodi".  Kodi originally started out as software called XBMC, that was developed for use on the original xbox. You should care because with an HTPC and free software such as Kodi (but also with dedication and time because you have to acquire all your media), you can browse your entire media collection, as well as a handful of online content on your screen in a format that was designed for viewing from a distance. https://www.youtube.com/watch?v=f_mU8JSk5dU I've been using it for many years, mostly because I absolutely CAN'T STAND the way it feels navigating my media through windows explorer or the file browser.  This way it feels as though I am on a console or a special device that was made for my content, even better with a PC remote I can navigate everything just like tv.  To make things even better, with the PsuedoTV Live addon you can take things such as folders, youtube channels, podcasts etc and assign them to channels (1 - 900) you can watch and surf through just like broadcast television. This takes more effort than netfux though, since you need to download everything yourself.
