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).
