Smart TV Channel Vote

Like usually I always have a very innovative and creative mind, always full of new exciting ideas and projects.
It came to me that why there hasn't been made any app for a smart tv that makes you able to vote for a specific show.

It would come in handy both on saturday night with the family, plus on a bar for instance.
Everyone would turn their phone on and vote on the show or program they wanted to see.
It would show the program with the most votes, so if it started out on tennis, and there suddenly when the world series came on at 19 it would thrive with football fans all voting for a specific channel it would change to this since there would be more that wanted to see that show.
Later on a reuning of a ishockey campus comes in and it would change to hockey since they were the most to vote for that.

Of course there would be a timeframe to be able to vote for a show/program, and in the same way it would change which programs you could vote on.
30% in the football match another show on another channel would end, and suddently there would pop up a new program the user would be able to vote on.

It could be really easy to make a voting mode on the tv, and thereby make family nights very easy and democratic and in the same way for sportsbars or other places make it interactive in a natural way.
