Months after denouncing social media as a "menace to society," controversial billionaire George Soros is again investing into Facebook, Twitter and streaming services Spotify and Pandora, while scaling back his Google holdings. With hedge funds filing their second-quarter statements with regulators this week, it has emerged that Soros Fund Management LLC is once again investing in Facebook. The fund has also bought shares in Twitter and the two streaming platforms, while selling off some stock in Google's parent company Alphabet Inc. and Amazon.com.
