That would be a great idea,many people are willing to watch that advertise,it's helpful because there are many people who don't understand about bitcoin like my family they're not believe in bitcoin. It's helpful to many bitcoiners.
You are right. If we want to make bitcoin popular and we wish it definitely. Then I must say the developers should take an eye on this account and make bitcoin famous. On planet earth, every house have TV so that will be the best method to take bitcoin at such a low level areas too. This all will upgrade the fame of bitcoin and thus the market will be making such huge profits at the end of day.
The government manage the Television programmer, I do not think they will accept to add Bitcoin into the Television program.
Because, most of the countries are neutral to decide the rule for Bitcoin or do not accept it in their country.
