Google is joining Samsung in launching a full push against Apple on TV. The search engine is running its own Galaxy Nexus commercial (below), produced by ad agency Mullen, on TV in the US, Canada, Japan, and other countries that have the Nexus as an option. One of its initial 30-second spots touts Face Unlock, showing how a father can keep his son from getting into the phone despite the young one's repeated attempts to look like his dad.
