To avoid copyright violations, Amazon does not return the computer-readable text of the book. Instead, it returns a picture of the matching page, instructs the web browser to disable printing and puts limits on the number of pages in a book a single user can access. Additionally, customers can purchase online access to some of the same books via the "Amazon Upgrade" program.
Although As Seen On TV was founded in the 1980’s by Shark Tank panel member Kevin Harrington, the public domain label is often used to refer to all infomercials that have aired to date – ranging from the familiar Ron Popeil and his line of popular “o-matic” products, to Sir James Dyson and everyone in between. The infomercials all use direct marketing which allows customers to immediately understand the benefits of a product, and provides the seller with an easy way to track results and understand if a campaign will be profitable.
