Today's Tech: Samsung's Android dominance threatens Google, YouTube snags one billion users, Twitter celebrates seventh birthday

Samsung has become a force to be reckoned with in the mobile market. With its Samsung Galaxy devices, it is outselling not just other Android OEMs, but even beating Apple at various times.

To put that into perspective, YouTube would be the world's third largest country after China and India if its viewership were a geographic entity - and we're sure there would be no shortage of takers for the title of Supreme Leader of Omgcutecatland.
