According to BI’s Nick Carlson: after years of hammering away at Apple's share of the smartphone market with cheap-to-free Android phones, Google has lately adopted a new tactic to win mobile.
Call it "the worm strategy"—because Google is attacking Apple from the inside out. Over the past six months, Google has begun to systematically replace core, Apple-made iOS apps with Google-made iOS apps.
In July, Google launched Chrome for iPhone—a Safari replacement. Then, in October came Google Search—which included a voice search feature to compete with Siri. In December, Google launched Google Maps to replace Apple Maps, and a much-improved Gmail to replace Apple's core Mail app. It also put out a new YouTube app, to replace the one that Apple removed during its last iOS upgrade.
Google doesn't plan to stop there…..
