This multimedia buffet of art history began in 2005 when Pratt Institute Prof. Steven Zucker and Museum of Modern Art digital learning director Beth Harris started a blog with free audio guides to New York art museums. Now the site includes hundreds of videos of art historians in conversation about selected art works. The beautifully designed homepage gives you a portal into the videos by timeline or by geographic location. Most videos are 3 to 10 minutes long, and can be viewed on the site or downloaded from the site or from iTunes.
Some of the video images are unfortunately a bit small (see sample above), but you can often get a better look at the art work under discussion by clicking on over to the Web Gallery of Art, and searching for the art work by name or by artist.
