The document outlines key changes and milestones in the development of major UK supermarket websites between 1996-2015. Sainsbury's and Asda were the first to offer websites in 1996. Major developments included Asda splitting its homepage into sections in 2001, Morrisons getting its domain name in 2004, and supermarkets moving to single prominent images on homepages between 2014-2015. Supermarkets also redesigned homepages and logos over this period to keep up with digital trends.
