"... around 77 per cent was from ads served on its own sites"
"...50 per cent growth in its non-advertising businesses, including the Play store"
Now, are these 2 really not connected?
Anyways, if 77 per cent of ads where served from their own sites, wouldn't this be a bad thing? Unless google has millions of websites out there, then their effective advertising is shrinking to only what they own directly...know what I mean here? If this is really good news, then there must be a connection between the play store or google has put up more websites than .com squatters ever have.
