TV companies are in the business of selling you new TVs every few years, and to do that, they have to convince you that the latest gizmo is even better than your current gizmo. Resolution has proved to be one of the easiest ways to convince the average person that the new thing is better. "4K" was a brilliant marketing move. More is better, right? Well 8K is an even easier sell. 8 is more than 4, done and done!
