A game changer – the Internet 1
The Internet began to spread rapidly in the 1990s. In the world of business, especially retail, it has been a major game changer.
The whole retail landscape has changed since the 1990s. Online retail giant Amazon.com did not exist before 1994. The dominant shops and stores, in those days, consisted of physical buildings. Until about twenty-five years ago, online shopping did not exist.
Today, Amazon.com is one of the world’s largest companies in the retail sector.

Companies that did not adapt to the online world did not survive. Wikipedia has a list of hundreds of retailers in the United States that went out of business. Most of Wikipedia’s list consists of companies that went out of business after the Internet emerged.
