Free Technology for Teachers

I have been to the site more than one time and I noticed the content changes frequently which is nice.  The technology that drew my interest was Snag Video, it is a series of educational videos documentary style which are mostly socially related.  The videos are free and most importantly, current.  Being current in  a class like I teach (Global Studies) is very useful.  Funds are not always available to replace tapes and DVD's  which are no longer relevant.  A site like this would definitely help.  They did mention there are commercials on the clips, a small inconvenience in my opinion for up to date material.
