In the "Platform" battlefields you have Microsoft, Apple and Google fighting for the end-users. On the infrastructure side Amazon is also making a play here with all of the AWS options and Google and Microsoft are also fighting there.
In the "Social" battlefield, you have Facebook, with Microsoft+LinkedIn+Xbox carving out some niches and Google flailing wildly at everything.
In the "Creepy Stalkering" battlefield (which overlaps some with Social) you have Facebook getting people to give up data and Google just silently watching .everything.you.do. muahahahaha. Facebook also watches as much as possible via website badges and sharing, but doesn't have near the reach of Google with searches + Analytics.
I'm sure there are other battlefields I'm not listing here including things like overlap into the offline world ("Political Influence" anyone?), but it's far from just a 2-sided battle.
