google announces Official URL shortcut for its services - g.co
A bigger URL in not a better option. Hence, google , in 2009 launched the first shortcut for its users, goo.gl .
Today, google announced a shorter Official URL. This URL, g.co is a shorter URL to access all google services. Keeping in mind that a simpler and shorter URL is always easier for a user to share and to remember. g.co will redirect to pages owned by google. Also, if you are goo.gl user then you dont need to worry, because the goo.gl URL service wont be affected by the launch of the g.co URL. It will continue to be google's URL open for public. Google was helped by the .CO internet SAS(who operate these .co domain names) for acquisitioning the new URL for google g.co.
