"On July 15, 2003, Time Warner (formerly AOL Time Warner) disbanded Netscape. Most of the programmers were laid off, and the Netscape logo was removed from the building."
Peak Netscape was 1996. By 2003, they had already handed development off to Mozilla, and Netscape the browser was just a thin veneer over Mozilla's browser.
By 2007, it was just Mozilla with AOL branding and almost all of it's users were people still using AOL in 2007.
