Is Apple a phone carrier not a consumer electronics company, since a huge chunk of their revenues come from carrier subsidies that lock consumers into multiyear contracts that obfuscate the true costs (e.g. $2200)? Google is spending so much of its revenue on other ideas like Glasses and self-driving cars, not for PR purposes, although it does garner positive PR, but because getting 95% of you revenue from a single source is risky in the long term, and they are obviously trying to diversify. If you want to describe Google as an advertising company, go ahead, but that is a grossly under-descriptive term of what the company truly does, as poor a description as calling Amazon just a retail store.
