Scott Vivian has written an article on PageRank domains with a PageRank of 9 and 10.

He says:
Wikipedia had a page listing known websites with a PageRank of 10, and a large number of sites with PageRank 9. However it was decided that the page contradicted Wikipedia's article policy and so was deleted. (Personally I found it a great resource, but their rules are there for a reason, I guess.) Anyway, since I haven't seen it replicated anywhere else on the internet, I have put a copy here on my site for anyone who misses the Wikipedia page to view.

The PageRank 10 obviously includes many commonly known names such as:

• Adobe.com - Adobe Systems, software company
• Apple.com - Apple Computer, also houses the iTunes Music Store
• NYTimes.com New York Times, news site
• Google.com - Google, search engine that assigns PageRank
• Whitehouse.gov - The White House 

The PageRank 9 list is however too large. Some of the sites that have made it to Page Rank 9 includes:

• AlltheWeb.com - AlltheWeb, search engine
• AltaVista.com - AltaVista, search engine
• Amazon.com (redirect) - Amazon.com, shopping site
• Britannica.com - Encyclopedia Britannica
• Disney.com
• eBay.com - EBay, auction site
• Mozilla.org - Mozilla, open-source Internet tools
• MSN.com - MSN.com, portal
