Today marks the first anniversary of Google’s Gmail email service, and the company has doubled the storage space to 2GB, up from its present 1GB offering, reports AP. The change takes effect today and Google says this increase will not be the last. The company said it will continue to increase storage space based on its user’s needs. “Our goal is to make sure storage is no longer an issue for Web mail users,” said Marissa Mayer, Google’s director of consumer Web products.
