You cannot possibly have missed the relentless ads for CNN's October "Planet in Peril" documentary, a four-hour eco-soap starring Anderson Cooper, Dr. Sanjay Gupta, and (of course!) Animal Planet's Jeff Corwin, the impoverished man's Steve Irwin. The "CNN Worldwide Investigation" (oooh...heavy) took a year to complete, cost the network some serious change, and was hailed as its first high-definition documentary, following the fall launch of CNN-HD. Too bad that sister-company Time Warner neglected to get with the freaking program already—the largest cable provider in New York and LA still doesn't carry CNN in high-definition.
