Will Facebook make a car? Zuckerberg: Focus on the network

No cars and solar power for Facebook, it seems.

Asked at a town hall event at the Mobile World Congress in Barcelona, Spain, if the world's biggest social network had ambitions outside of social media and the Internet, CEO Mark Zuckerberg said Facebook is "pretty focused."

Apple has created phones, music players and computers and is rumored to be working on an electric car. Google has a driverless car, has invested in solar power and is working on cancer-detecting pill.

Nonetheless, Facebook's goal of connecting people globally is "pretty broad," Zuckerberg said. That includes enabling people to share their own photos and videos and message each other as well as giving businesses a platform.

Facebook is also trying to get more people in developing countries online through its Internet.org push and developing its virtual-reality technology.

Facebook streamed the question-and-answer session with Zuckerberg.
