"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]
Barnes & Noble sued Amazon on May 12, 1997, alleging that Amazon's claim to be "the world's largest bookstore" was false because it "...isn't a bookstore at all. It's a book broker." The suit was later settled out of court and Amazon continued to make the same claim.[36] Walmart sued Amazon on October 16, 1998, alleging that Amazon had stolen Walmart's trade secrets by hiring former Walmart executives. Although this suit was also settled out of court, it caused Amazon to implement internal restrictions and the reassignment of the former Walmart executives.[36]

The first Echo came out in late 2014 as a Prime member exclusive, but in the four short years since, Amazon has developed dozens of different smart home products that revolve around the speaker and voice assistant format. Today, thousands of products integrate with the company’s Alexa platform to make use of its voice search and query capabilities. Just as it once foresaw e-commerce, streaming, and cloud computing as the future of the internet, Amazon saw AI as not just something that could live within the smartphone — as Apple established with Siri and Google with its Assistant — but also in the home.
Even so, the first infomercial of the same type we see on TV today, aired in 1982 and was for a hair growth supplement called “New Generation” which was marketed by entrepreneur Robert E. Murphy Jr. It was such a success that other companies quickly began following suit and purchasing program-length commercial air time. At this time infomercials used to commonly be shown during late night/early morning hours, although stations discovered success showing them at other times when they learned that the majority of purchases were made in the morning, during the day, and around primetime.
