Nielsen/NetRatings reports in their Monthly Featured Analysis on the Top 10 Online Web Brands, ranked by fastest year-to-year growth. Apple is #1, having grown 57% over the past year, thanks to iTunes. Google is second (29% growth), followed by Amazon (16%), MapQuest (13%), and Real (12%).

Even if you clicked through to the PDF of the release to get the rest of the top 10, you may not have noticed the section at the bottom of the release: “Younger Visitors Hit Fastest Growing Web Sites.”

Among the 12-24 set, social networking sites MySpace, Facebook, and Memegen (make your own quiz!) have grown 752%, 530%, and 446% respectively. They rank second through fourth. Photobucket, used to host many of the photos that appear on those sites, was number one, growing 1,492% (that’s not a typo).

Takeaway for marketers: If any of this comes as a surprise to you, it’s time to go read this Business Week article about the “MySpace Generation.”
