Google Glass should be worth $3.27 billion to Google in 2017, says one financial analyst who has been wearing the device and showing it to investors. Even with zero profit margin, Google should be able to make money from Glass via additional searches, better targeting from increased data collection and revenue share from app sales. By 2017, Google Glass should have an installed base of 64,500, and new units should sell for $349, estimated Robert S. Peck of SunTrust Robinson Humphrey, in a research note. And the face-mounted computer display should bring in $3.27 billion in non-hardware revenue that year, or 3.7 percent of an estimated $86.4 billion 2017 total revenue, Peck said. That will be primarily from search ads on Glass that fulfill prompts like “Okay, Glass: Google ‘pizza nearby.’”
