America Online is in talks to purchase Netscape in an all-stock transaction that is said to be worth in excess of $US4 billion, according to numerous press reports appearing over the weekend. The press reports, appearing on US television, radio and online versions of the Wall Street Journal and Newsweek, said that Sun Microsystems, may also be involved in the deal. The leaked details include AOL taking over Netscape's Web portal, or "Netcenter" as well as Netscape's popular Web browser software. Reportedly, Sun would take over the enterprise side of Netscape's business and pay AOL a fee for using Netscape technology. Netscape currently sells a number of business applications, including those used for messaging, groupware, and electronic commerce applications.
