ATW and AV will merger into the new Yahoo soon (not Inktomi) and therefore show Yahoo serps. The AV and ATW domains will therefore still be online as they in fact still are very well known brands (at least AV is being used quite a bit I'm being told).
Bye bye good old search engine technologies. It was fun and you'll be missed as part of the mix.
Gates's MSN will eventually win out on top in the long run. Whe? Well MSN has an exclusive broswer partnership with AOL. Also, they control the desktop market. Believe that when the next update to XP & 2000, somewhere in that update will be the new and improved MSN Search. Also, when longhorn comes out, it will have search built in to the desktop.
So, the only question is.... Which company will join the MSFT family of web sites? Google or Yahoo? I would tend to guess that Google is in worse condition than Yahoo, so that might very well be a good takeover target for CHMN Gates. If they were in better shape, the IPO would have had a set date by now. Only time will tell...
