The last decade has been defined by Microsoft giving up share mostly to Firefox, the one successful offspring of Netscape’s Navigator, with this market share decline becoming one of the most visible examples of Microsoft not being able to compete in this space anymore. Netscape came along and slapped Bill Gates, causing Microsoft to counter-punch Netscape into obsolescence with a free browser in the form of Internet Explorer. Back in the 90s, Microsoft was focused on AOL, consequently creating MSN to combat what was then thought to be the biggest threat to Microsoft’s dominance.
The browser wars were defined back in the day when Microsoft was the underdog.
