As livable streets advocates work to make headway in breaking the cycle of American auto dependence, the folks at Planetizen have put together a video narrative that explains how we got here. "The Story of Sprawl," a double DVD set produced by Managing Editor Tim Halbur, is a compilation of historical films dating from 1939 to 1965, documenting the confluence of factors that fostered the quintessential land use motif of the 20th century: far-flung, low-density, driving-intensive residential and commercial development. The discs include commentary from planning notables including Andrés Duany, Elizabeth Plater-Zyberk, John Norquist, Neal Peirce, James Howard Kunstler and Robert Cervero, featured in the clip above.

"The Story of Sprawl" is available now. Check the Planetizen promo page for more clips and ordering info.
