...we’re going to begin testing variations of Chrome’s New Tab page (NTP) in which a user’s default search provider will be able to add a search box or otherwise customize the NTP. While you can search straight from the omnibox in Chrome, we’ve found that many people still navigate to their search engine's home page to initiate a search instead. The goal is to save people time by helping them search and navigate the web faster.
Starting today, a small set of users on Dev channel on Windows and Chrome OS, who have Google selected as their search provider, will begin seeing variations of the new experience. Mac will be coming soon.
