With all the modular phone concepts, balloon internet projects, robots and drones it can be easy to forget Google's main business angle: search and advertising. Google reported its first quarter earnings today and didn't have much to say about our favorite topics -- we'll hear more about those at Google I/O in June -- or even its pending sale of Motorola to Lenovo. Responding to an analyst's question, Google execs Patrick Pichette and Nikesh Arora mentioned the need to "keep evolving (search) results," as it increasingly serves up info (sports scores, TV listings, restaurant menus) on its own website instead of just providing links. That's probably also behind its push for Google Now results that bring up relevant info before the user even asks, on the desktop and mobile. In a brief reference to the Chromecast, Pichette called the $35 device a hit, mentioning the over 3,000 developers had signed up to build apps since the launch of the SDK.
