"Search Inside the Book" is a feature which allows customers to search for keywords in the full text of many books in the catalog.[126][127] The feature started with 120,000 titles (or 33 million pages of text) on October 23, 2003.[128] There are about 300,000 books in the program. Amazon has cooperated with around 130 publishers to allow users to perform these searches.[citation needed]

Amazon's state sales tax collection policy has changed over the years since it did not collect any sales taxes in its early years. In the U.S., state and local sales taxes are levied by state and local governments, not at the federal level. In most countries where Amazon operates, a sales tax or value added tax is uniform throughout the country, and Amazon is obliged to collect it from all customers. Proponents of forcing Amazon.com to collect sales tax—at least in states where it maintains a physical presence—argue the corporation wields an anti-competitive advantage over storefront businesses forced to collect sales tax.[165]

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.
