Persuasive Design: Amazon

I'm not sure when Amazon introduced this feature but they've started putting internal advertising in the top left hand corner of the screen, where the logo used to be.

A couple of time now I've clicked it expecting to go the homepage, but instead I was taken off to the jewellery section or the new musical instrument section. Frustrating but a great way to drive people to a new or hardly used sections of your site.

Persuasive computing at work.
