Development hypothesis of goolge and Gmail account

I didn't expect Google to develop so fast that she launched new content almost every day.

Since the past year's Gmail was launched in a form of "Hunger" sales, many of her content was centered on the Gmail account.
Google accounts must be based on a Gmail address to provide accounts for many subsequent services.
Such as Google Talk, Google group, Google Adsense, Google Page creator, Google serarch, Google Blog and so on...

I was lucky to have obtained a Gmail account a long time ago. Now the Gmail account is nothing new, but many people only think that Gmail is just a normal mailbox, however, I thought about it a long time ago that Google's subsequent products will be centered around Gmail accounts. If you want to use Google's services, you have to have at least one Gmail account.

Add a Google icon (not all at all ):

In addition, if you want a Gmail account, leave an email address. (Although this is already quite old)
