web pages, PCs, searching : Billions for Google
mobiles, mobile app (where no need for Google search) : Nothing for Google.
Google is heavily invested in keeping the current paradigm of the Web, where it is by far the biggest money-maker. While most content companies and software developers struggle to make the kind of money on the Web that they did with their previous business models, Google continues to rake in billions with its AdWords and AdSense programs. On today’s Web, Google is the home team. Chrome OS would only strengthen that position, while Apple iOS and Android threaten it by moving eyeballs from Web pages to apps, with a much more focused and granular experience (and little to no room for AdWords and AdSense).
