NEW YORK ( TheStreet) -- eMarketer is out with updated mobile advertising-revenue projections.

If you (A) do not believe in the mobile revolution, (B) doubt Facebook ( FB - Get Report) as an advertising platform powerhouse and (C) discount Pandora ( P) as the dominant player in Internet radio, you probably still question global warming and want the study of evolution out of public schools.

Dig these numbers. More importantly, dig the change between the two sets of data.

It doesn't take a scientist who deals in rockets to see that Google ( GOOG - Get Report) continues to take over the world. But just look at the bump up in the Facebook, Pandora, Twitter and Apple ( AAPL - Get Report) numbers.

The takeaways here debunk two myths.

One, that Facebook does not provide an effective advertising platform. It absolutely does. If it doesn't work for your favorite company's brand, hire new social media people, because the current crop isn't doing it right.

Two, that Pandora is not for real. Do any other Internet radio players show up on eMarketer's list? Have they ever? Where's Pandora-crusher Spotify? Not there because, at day's end, it doesn't have a business. At least not one built out to the scale that Pandora's is. Without scale and a sales infrastructure -- both could take years to build -- it's difficult, if not impossible, to compete.
