Internet Explorer was once the top web browser

Internet Explorer was once the most widely used web browser, attaining a peak of about 95% usage share by 2003. This came after Microsoft used bundling to win the first browser war against Netscape, which was the dominant browser in the 1990s. Its usage share has since declined with the launch of Firefox (2004) and Google Chrome (2008), and with the growing popularity of operating systems such as Android and iOS that do not support Internet Explorer. Estimates for Internet Explorer’s market share are about 2.28% across all platforms or by StatCounter’s numbers ranked 7th, while on desktop, the only platform on which it has ever had a significant share (e.g., excluding mobile and Xbox) it is ranked 4th at 5% after macOS’s Safari. It manages to reach the second rank after Chrome when its statistics are combined with its successor, Edge (others place IE 3rd with 7.44% after Firefox). Microsoft spent over US$100 million per year on Internet Explorer in the late 1990s, with over 1,000 people involved in the project by 1999.
