Google joins the internet biggies Twitter (T.Co) , Overstock (O.co) and Amazon (A.Co, Z.Co and K.Co) today in taking over the G.Co domain name.
G.CO, the new URL shortcut will only link to official Google products and services like GMail, Documents and Photos. Whenever you see a short "g.co" link, you can trust that it will always take you to a Google product or service.
The public URL shortener, goo.gl is available to shorten up URLs across the web.
