Facebook shares rise as Zuckerberg to sort mobile errors

Facebook’s stock price has risen after chief executive Mark Zuckerberg said he is addressing the missteps that have made it hard to reap the benefits of mobile advertising.

“Now we are a mobile company,” Zuckerberg said in an on-stage interview at the TechCrunch Disrupt conference in San Francisco, his first since Facebook’s initial public offering.

“Over the next three to five years I think the biggest question that is on everyone’s minds, that will determine our performance over that period, is really how well we do with mobile.”
