Amazon allows users to submit reviews to the web page of each product. Reviewers must rate the product on a rating scale from one to five stars. Amazon provides a badging option for reviewers which indicate the real name of the reviewer (based on confirmation of a credit card account) or which indicate that the reviewer is one of the top reviewers by popularity. Customers may comment or vote on the reviews, indicating whether they found a review helpful to them. If a review is given enough "helpful" hits, it appears on the front page of the product. In 2010, Amazon was reported as being the largest single source of Internet consumer reviews.
Since its founding, the company has attracted criticism and controversy from multiple sources over its actions. These include: supplying law enforcement with facial recognition surveillance tools; forming cloud computing partnerships with the CIA; luring customers away from the site's brick and mortar competitors; placing a low priority on warehouse conditions for workers; participating in anti-unionization efforts; remotely deleting content purchased by Amazon Kindle users; taking public subsidies; claiming that its 1-Click technology can be patented; engaging in anti-competitive actions and price discrimination; and reclassifying LGBT books as adult content. Criticism has also concerned various decisions over whether to censor or publish content such as the WikiLeaks website, works containing libel and material facilitating dogfight, cockfight, or pedophile activities. In December 2011, Amazon faced a backlash from small businesses for running a one-day deal to promote its new Price Check app. Shoppers who used the app to check prices in a brick-and-mortar store were offered a 5% discount to purchase the same item from Amazon. Companies like Groupon, eBay and Taap.it countered Amazon's promotion by offering $10 off from their products. The company has also faced accusations of putting undue pressure on suppliers to maintain and extend its profitability. One effort to squeeze the most vulnerable book publishers was known within the company as the Gazelle Project, after Bezos suggested, according to Brad Stone, "that Amazon should approach these small publishers the way a cheetah would pursue a sickly gazelle." In July 2014, the Federal Trade Commission launched a lawsuit against the company alleging it was promoting in-app purchases to children, which were being transacted without parental consent.
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.
