Gmail introduced the People Widget last month and began to roll out the new feature slowly to all Gmail users. People Widget is a small contextual sidebar to the right of your email messages that features information about the people you’re communicating with in Gmail.
It features the job title of the person whom you are interacting with, recent emails exchanged, photo, calendar availability, and shared Google Docs. People Widget, however, is only restricted to Google’s services like Google Calendar, Google Buzz, Google Docs and so on. It does not share third-party services like Twitter and Facebook.
Some users like you find the information widget quite annoying and that is why you are here. Here’s how you can remove and get rid of Gmail’s People Widget.
Go to your Gmail Settings on the top-right corner of your Gmail page.
On the General tab scroll down, and in the People Widget section, select Hide the people widget.
Click Save. You’re done. The widget will never appear again until you enable it.
