Mainstream medias in TV/Magazines/Radio are one of the reasons the information is spreading really fast so need to make more educations about Bitcoin so people stop looking at one side only but they have to know about the good use of Bitcoin and they probably don't even realize that they have been using the technology behind Bitcoin for their entire life.
I really think that dissemination through the media is one of the most effective ways to spread education and understanding about Bitcoin and reach the wider community.
But unfortunately, as long as the government in a country doesn't regulated Bitcoin or doesn't support Bitcoin, I think we won't be able to disseminate education about Bitcoin on TV, magazines or even radio. I don't think it can be used as a dissemination of Bitcoin education because all of their programs will be subject to the rules in force by the government of that country.
It's a different story if their government has regulated or even legalized Bitcoin, of course it will be easier to spread Bitcoin education through TV, magazines and radio media. Maybe they can even make a special tv show to provide understanding and education about Bitcoin to educate the citizens of their country.
