Facebook-owned virtual reality headset maker Oculus' Co-founder Brendan Trexler Iribe on Monday announced he is leaving Facebook. "After six incredible years, I am moving on...this will be the first real break I've taken in over 20 years," Iribe said in a post. Oculus, which makes Oculus Rift and Gear VR headsets, was acquired by Facebook in 2014 for $3 billion.
