"Imagining America: Icons of 20th Century Art" (9 p.m., PBS): Television doesn't actually take a post-Christmas vacation, but it might seem that way as you're slogging through a week riddled with moldy reruns. Still, a freshly absorbing and worthwhile viewing experience is available in this documentary special, which traces the evolution of the United States in the 20th century through the eyes of its pre-eminent artists. Relying on a glorious barrage of images, as well as interviews with artists and art historians, "Imagining America" traces how art, over the course of the century, provided a place in which to re-imagine America, to visualize what we were and what we felt about our country, our society and ourselves. Among the legends featured in archival interviews are Georgia O'Keeffe, Jackson Pollock, Lee Krasner, Willem de Kooning, Marcel Duchamp, Andy Warhol and Jean-Michel Basquait.
