“The logic for Facebook’s price decline is that they have a problem in mobile. They can’t offer all the games they can in a browser. They can’t offer the same ads or branding opportunities. All true,” he writes. “If you think mobile will displace online usage from PCs then you should immediately short Google and other ad plays and buy TV stations and networks. If you can’t buy an ad effectively on mobile and no one is using a PC to connect to the internet any more, then the only way to reach an audience is going to be via good old tv. And all that over the top video noise, forgettabout it.”
