Prime started as a two-day shipping membership for devoted Amazon shoppers, and it didn’t add any additional benefits until 2011. However, since then, Prime has grown into a subscription service with more than 100 million paid users worldwide, while the service itself has evolved to include additional perks over the years, including a Prime credit card now with 5 percent cash back. (Amazon also operates Amazon Pay for purchasing online goods elsewhere with your Amazon account, and the Amazon Cash service for translating cash into store credit using a barcode, although neither are restricted to Prime users.)
The domain amazon.com attracted at least 615 million visitors annually by 2008. Amazon attracts over 130 million customers to its US website per month by the start of 2016. The company has also invested heavily on a massive amount of server capacity for its website, especially to handle the excessive traffic during the December Christmas holiday season.
According to an August 8, 2018 story in Bloomberg Businessweek, Amazon has about a 5 percent share of U.S. retail spending (excluding cars and car parts and visits to restaurants and bars), and a 43.5 share of American online spending in 2018. The forecast is for Amazon to own 49 percent of the total American online spending in 2018, with two-thirds of Amazon's revenue coming from the U.S.
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.
