Daniel Peterson runs the world’s biggest virtual-reality website. It just happens to be dedicated to porn. He claims his site, VRporn.com, gets 10.5 million views per month. According to SimilarWeb, this is almost double that of Oculus.com, the website for the VR company that Facebook bought for $2 billion (£1.5bn) in 2014. “I don’t want to say we’re a big deal, but we are kind of a big deal,” Peterson says.
