Google has a huge revenue generating machine in search, and adwords. This allows them the opportunity to spend massive amounts of money on a lot of projects that will mostly fail. They're hoping, at some point, one or more of these projects will turn profitable. But they're burning millions doing it.

The problem with this approach is that they end up neglecting their core search product, which I don't think has evolved much in the past decade. If someone else comes along and disrupts search, its goodbye Google.
