Google has been serious about boosting hardware revenue as it looks to expand into other businesses outside of its core search and advertising segments. Though Google missed earnings estimates last quarter as costs-per-click (CPC), a key advertising metric, continued to be weak, the company generated $1.05 billion in Other Revenue, which includes hardware sales. That figure rose 138% year over year, so it's clear that Google is increasingly focused on building this part of the business. Motorola Mobility accounted for $998 million in revenue last quarter. Google does not break down how many smartphones or tablets it sells each quarter, as Apple does, but the company noted continued momentum in hardware during its second-quarter earnings call . "
