If you think watching advertisements on purpose is fun, you'll want to check out the selections at iAdChoice where they rate and recommend Chinese video clip ads, interactive websites, animated ads, rich media ads, and more.  You can also search by industry rather than format, as in transportation or health ads. iAdChoice seems to be an arm of iResearch, which has an extensive English language presence, but it's not the same as the Chinese. If you want to browse and you don't read Chinese, do this:

go to any of the links above.  Currently on the recommended video clip ads is one for the hip Toto Neorest toilet.  Under the picture of the display screen for the ad is a hyper link that looks like this:

Click on it and it will bring you to a window that runs the ad itself. There's also an ad for the iPod Nano available, and a perfume ad for Guerlain.  Browse the hyperlinked ads at the very bottom to fine Chinese domestic brands like the sports apparel provides Anta.
Enjoy!
