Copyright © "COMPANY", 2010.
I realise most people update the date in the copyright notice to reflect the current year (which is easy to do on a dynamic webpage) and this does seem to be accepted usage. However, I have always been under the impression that strictly speaking this should be the date/year the document was initially created (which is how it works with printed material). Only if the document is sufficiently updated at a later time should the year of copyright be updated.
Copyright does not expire at the end of the year, so a document that states "Copyright © 1997" is still under copyright in 2010.

Interesting to note that:
Some countries will not accept the symbol alone, they also require the word Copyright to appear in order to consider the notice valid. Using the word ensures that there can be no confusion.
eg. Copyright © 2004 Bobby Smith.
Which in some ways conflicts with what @Marco has quoted above regarding US Law. Either the symbol OR the word, not necessarily both?
