In an event yesterday that was streamed and watched across the globe, it  also introduced upgrades to two apps - Google Play Music and Google Photos.

Before announcing the latest releases - two smartphones Nexus 5X and Nexus 6P, second generation Chromecast, an audio Chromecast and a new 10.2-inch tablet named Google Pixel C, Pichai said, "It was great receiving the Indian Prime Minister Narendra Modi to the Silicon Valley."

PM Modi made a two-day trip to the West Coast where he met chief executives and founders of several top technology companies during his five-day US visit.

According to Google, the company has added 400 million new users to the Android ecosystem in one year. "Previously we had one billion 30-day period active users but now we have 1.4 billion 30-day active users," Pichai said.

"With people in emerging economies moving to smartphones especially with our Android One initiative that offers high-quality yet affordable smartphones, we are on route to meet the target of getting the next billion users online," he said.

He also said that more Chromebooks were being adopted in the US schools. "Nearly 30,000 Choromebooks were activated in the month of September alone. Our 'Android for Work' is also picking up with 10,000 firms already adapting it partially or completely," he said.

The company's latest iteration of the Android OS - Marshmallow - was also introduced yesterday. Google, which had first announced  Android 6.0 Marshmallow at its I/O developer conference earlier this year, said  that the new OS will be available to users on Nexus devices.
