Basically started as a search engine right? They get paid for the advts..
But they offer users a lot like.. gmail, google+, maps (scanned down the whole world.. navigation works amazingly even in remotest parts of India
), youtube, news
, docs, calendar, chrome, earth, android..
I meen, they offer users a lot.. but it seem that they have less options to make money out of it right? like android market, advts? Really how do they make enough money? I cant understand
