If you need more evidence of the pervasive reach of iTunes and YouTube, check out the Internal Revenue Service's newly launched videos and podcasts. The tax man offers digital information about tax provision of the economic stimulus legislation (officially the American Recovery and Reinvestment Act) and other topics via talking heads and more on YouTube. Podcasts are also available in English and Spanish at the IRS's "multimedia center." It's great material, if you thrill for demonstrations on how to use the IRS Withholding Calculator and similar subjects. All it needs are some hip-hop background tracks.
