Er, those are both insanely large industries with untold amounts of money flowing through them (well, radio not so much but in its heyday).

If FB is an industry on the level of TV or radio, then it's almost certainly not overvalued.

Yes it is company that is larger, more influential, and more relevant than the entire industries of TV or Radio and even print/online journalism at large.

The implications and consequences of the consolidation of this power and influence into one company is a different discussion entirely (and an important one).

FB is better than tv and radio because it can give you ads that are more likely to affect you, because it knows you, maybe better than you know you.
