What is the most popular website?

2007-06-12: Since the Internet is not run by a single company or government, there is no perfect way to identify the most popular website. However, there are companies out there that work hard to "measure the web" and figure out which sites are receiving the most traffic. One of the best-known companies of this kind is Alexa.

alexa.com provides free access to their list of the top 500 websites. As of June 12th, 2007, Alexa ranked www.yahoo.com as the #1 most popular website in the world.

Alexa can also provide you with information about the popularity of your own site or any other site that you search for.

That much, they offer for free. Alexa also offers professional products, such as a database of the top 10,000 websites, for a hefty but not necessarily unreasonable price.
