And now for something different.

The Computer History Museum in Mountain View, California hosts digital exhibitions, including a timeline for computing history, a history of the internet, and a history of microprocessors. There is also an exhibit called Selling the Computer Revolution: Marketing Broshures in the Collection, which offers both small images and full-size PDF files. The museum is not just for engineers. Much of the material is accessible to ordinary people who have no clue about how the magic inside their computers works.

Also worth a visit is PC World's A Brief History of Computers, As Seen in Old TV Ads, which contains lots of clips from the early days of home computing.
