Google has done some recent reorganizations of positions within the company, and that re-structuring has led to CEO Larry Page putting Sundar Pichai in charge of basically all of Google's core products. This means that he not only oversees Android, Chrome, and Google Apps, but also Google+, research, Maps, Search, ads, and commerce. This new push for Pichai means that he will now be the person to report to for anyone working in those divisions, something that Larry Page himself was previously handling. This move for Page stepping away from some of those roles he says will allow him to take a look at the "bigger picture," which should be a lot easier now that he won't be directly overseeing so many different segments of Google's operations and business.
Pichai still reports to page of course, but delegating some of those tasks to him will afford Page more time to re-focus on keeping Google innovative with new and existing products. Pichai has been at Google for around a decade now starting his time with the search giant in 2004, and has only recently(just within the last couple of years) started to pick up more responsibility as he began to oversee Google apps in 2012. In just a few short years, Sundar Pichai has gone from being the head of Chrome and ChromeOS, to head of Android, Google Apps, and now the six divisions he's been promoted to overseeing as of today.
Pichai has been at the forefront of many projects for Google, including the newly announced Android One program that was unveiled earlier this year at Google I/O, which will see the most affordable Android powered handsets yet find their way into emerging markets where more expensive flagship devices aren't typically within reach cost wise to most people in the regions. Although he now manages about nine different divisions for Google and is essentially the companies Senior Vice President of nearly all major products, the same sources that have stated Pichai's new positions also mention that he doesn't actually hold the title of SVP. Pichai has grown at Google quite fast in a short time period, and there's no doubt that he'll end up doing great things with his new roles.
