Yes, it's a very practical idea. In my country, there has not yet been a promotion of bitcoin on print media. I think the TV promotion is a good thing for many never contacted bitcoin people, because through the TV news and the new thing is their living habits, these media users is very large.
The news media will not bother advertising about Bitcoin, but if the government allows them to do such. But business discussion channels, or stock market discussion channels, has already talked and mentioned about Bitcoins, but they didn't advertised. So I believe it did helped the news coverage as it acted as promotion as well or indirect advertisement.
Recently I saw some unknown, never heard crypto ICOs which is being advertised in local newspapers.
