Founded in April 1996, Alexa Internet grew out of a vision of Web navigation that is intelligent and constantly improving with the participation of its users. Along the way Alexa has developed an installed based of millions of toolbars, one of the largest Web crawls, and an infrastructure to process and serve massive amounts of data.

For users of Alexa's Toolbar and web site this has resulted in products that have revolutionized Web navigation and intelligence. For developers this has resulted in a set of tools unprecedented in scope, allowing whole new services to be created on the Alexa data and platform.

OpenID eliminates the need for multiple usernames across different websites, simplifying your online experience.

You get to choose the OpenID Provider that best meets your needs and most importantly that you trust. At the same time, your OpenID can stay with you, no matter which Provider you move to. And best of all, the OpenID technology is not proprietary and is completely free.

For businesses, this means a lower cost of password and account management, while drawing new web traffic. OpenID lowers user frustration by letting users have control of their login.

For geeks, OpenID is an open, decentralized, free framework for user-centric digital identity. OpenID takes advantage of already existing internet technology (URI, HTTP, SSL, Diffie-Hellman) and realizes that people are already creating identities for themselves whether it be at their blog, photostream, profile page, etc. With OpenID you can easily transform one of these existing URIs into an account which can be used at sites which support OpenID logins.

OpenID has arisen from the open source community to solve the problems that could not be easily solved by other existing technologies. OpenID is a lightweight method of identifying individuals that uses the same technology framework that is used to identify websites. As such, OpenID is not owned by anyone, nor should it be. Today, anyone can choose to be an OpenID user or an OpenID Provider for free without having to register or be approved by any organization.

TED stands for Technology, Entertainment, Design. It started out (in 1984) as a conference bringing together people from those three worlds. Since then its scope has become ever broader.

The annual conference now brings together the world's most fascinating thinkers and doers, who are challenged to give the talk of their lives (in 18 minutes).

This site makes the best talks and performances from TED available to the public, for free. More than 200 talks from our archive are now available, with more added each week. These videos are released under a Creative Commons license, so they can be freely shared and reposted.
