IRS is using videos to explain some newer tax provisions.  You can view them at http://www.youtube.com/irsvideos .

There are a couple of dozen videos.  Most are in English, but there are a few in Spanish, and even some in American Sign Language.

Curiously, IRS has resisted such things in the past.  They continue to warn that they never send emails to taxpayers.  They even ask you to forward suspicious emails and bogus websites to phishing@irs.gov.
