Web Design

So I recently have been checking out company web sites for work. I am amazed at how many sites are outdated. I laugh every time I see a site that says "copyright 2007" at the bottom. It is nice to know that site hasn't been updated since 2007. I ran across one today that was 2005. So much has happened in the past three years in the web design/development field. If you are the web master of a site, please make sure the copyright is up-to-date.
I am also wondering how much companies rely on their web sites. There is so much a company can do through their web site, but do they pay hundreds of thousands of dollars to use software installed on their computers, rather than using the web to do the same thing?
