New Delhi: Search engine giant Google Inc is experimenting a Chrome extension named 'Tone' which broadcasts the URL of the current tab to any machine within earshot that also has the extension installed.

According to the company, Tone grew out of the idea that while digital communication methods like email and chat have made it infinitely easier, cheaper, and faster to share things with people across the globe, but actually made it more complicated to share things with the people standing right next to you.
