This is the problem with technology, it's pratically impossible to catch on. Yet, some people try. It gets worse when companies try to dump new marketing strategies to sell stuff and people fall for it. I remember when they started pushing 3D TVs and a lot of my friends sold their perfectly fine HDTVs just to have the 3D feature. Then they realized they would need a 3D Blu-ray player as well. Today, all of them regret spending the money on something they barely used. But they are already falling for the idea of curved TVs and / or 4K... even when there's no 4K content available. But this is a country were people still watch SD content on HDTVs, even when the channel is available for free on HD as well. And when you point that to them, they act like you're being rude! During the world cup, a famous tv presenter had a feature on her show, where she invited some brazilian celebrities and friends to her home to watch the matches. In one of the shots, a huge 4K TV appearared and showed a stretched 4:3 SD image of the match!
