Related to the snarky comments about how this relates to Google's search/advertising business...that raises an interesting question: why isn't this filed under Alphabet Inc. rather than Google? I thought that was the purpose of having Alphabet, to be the umbrella over old-Google's old and new businesses?

edit: I can answer my own question: this was published on December 3, 2015. But it was filed May 28, 2014, which was created in 2015.
