Two billion of seven billion people around the world have digital devices that own and share content, says Karen Cahn, general manager of branded entertainment, AOL-Huffington Post Media Group, during a keynote address at OMMA Video in San Francisco.

But by 2015, there will be 15 billion devices.

So Cahn says: "We better build stuff that is really good." Mountains of data, however, are an obstacle to some of this, she says.
