I'll have to respectfully disagree. While search is their main product, with AdWords being their main source of income, Google also has maps, local, docs/drive, gmail, google play, wallet, android, etc.

While it wouldn't be a 'giant' without search, search definitely helped increase adoption of their other products and gave them revenue to invest into other things (plus their moonshots).

most of these product being ad driven,with the exception of some cloud services,though I really doubt Goggle win that much money on google/drive. It can however scan your files for "metadatas"
