The buzz has begun. The new domains approved are .biz, .info, .aero, .coop, .musuem, .pro, and .name. Ask anyone the first three words that come to mind when you say Internet and one will almost always be dot-com along with web or surfing. Dot-com is forever chiseled into our brain directly associated with the Internet.
Old habits die hard.
The new domains will confuse the average everyday web surfer. With so many suffixes it will be harder to find the information they are looking for. Out of frustration they will, most likely, resort to the old standby, dot-com. Big businesses like IBM and Microsoft have already spent billions promoting their dot-coms in print, and media advertising. This is highly unlikely.
