Not surprisingly, most of Google's mobile revenue comes from ads, but the infographic does a good job of showing the interconnectedness of the Google ecosystem, including ads that link to Maps or calling. The really interesting stuff in the graphic comes from Google's other products like Google Now which don't necessarily have a monetization strategy yet, but the graphic explains how it could be part of the revenue stream in the future. Most paths do lead back to ads of course.
It's an impressive infographic, but it may be a bit too detailed and points to the general waste that infographics can be. The file is 1056x11982 and 1.8Mb in order to cram all of that data in, which is a bit absurd. At that size, few people are going to read it all anyway, so you might as well just write the text, which would at least be searchable. Still, there's some cool info if you want to poke through.
