2GB Gmail in color
Google celebrated the 1 year birthday of Gmail by doubling the storage to 2gb while Yahoo and others are still in the process of upgrading to 1GB.
Storage is an important part of email, but that doesn't mean you should have to worry about it. To celebrate our one-year birthday, we're giving everyone one more gigabyte. But why stop the party there? Our plan is to continue growing your storage beyond 2GBs by giving you more space as we are able. We know that email will only become more important in people's lives, and we want Gmail to keep up with our users and their needs. From Gmail, you can expect more.
