At the time, it was Internet Explorer vs. Netscape, and we were building Intranet web apps for Windows users, so our target browser was pretty much only Internet Explorer. Mostly because of the more advanced JScript and XML processing capabilities, and eventually HTAs and early XMLHttpRequest support that came with IE6. Surprisingly we never got into ActiveX components. Even back then, they seemed like a bad idea... :)
