Where does the news come from in Thailand?

Sometimes you wonder where the news comes from in Thailand. In Europe most magazines can not print news that has some kind of advertisement inside them because they risk paying more tax. But in Thailand you can be sure to see an article about a company if there is a big advertisement in the same issue. The news I took notice about this time was the Happy Dtac and the news was “Dtac use yourtube.com to get customers” hum people have been doing that for years now and I do not think The Nation will write about all my videos I been uploading to the Internet to get more traffic?
