Facebook chief executive Mark Zuckerberg testified before Congress in response to the privacy scandal engulfing his social network.
The 33-year-old faced questions from a joint hearing of the US Senate's commerce and judiciary committees. In his opening statement, he apologized, saying: 'We didn’t take a broad enough view of our responsibility, and that was a big mistake. It was my mistake, and I’m sorry. I started Facebook, I run it, and I’m responsible for what happens here'
“We’re undergoing a broader philosophical shift about how we view our role as a company,” he said. “For the first 12 and 13 years, we were focused on building tools. It’s not enough to just build tools. We need to make sure that they’re used for good.”
