Honestly I think TV ads is a pretty bad idea, firstly someone has to pay for them and second to that they just really aren't all that effective as it is so difficult to accurately target people. Targeted ads by facebook etc are far more effective but thankfully we already have the exchanges doing that for us in a way.
I disagree, if ever advertising bitcoin in T.V will come true, then it is more likely to be of equal effective than advertising in social media. There are lots of people who are fond of watching T.V too and it is a good way to spread some awareness to them about cryptocurrencies. We don't need to pay for the advertisements, we can just have a segment about it on different shows right?
