Discovery Communications [3] is spending $100 million to re-make its home television network into "Planet Green," the first television channel devoted entirely to environmentally-themed programming. Programs will feature "green" Hollywood stars like Leonardo DiCaprio, rocker Tommy Lee and rapper Ludacris, and will show viewers how to remodel their homes and cook using environmentally-friendly methods and materials. But the "exclusive automobile sponsor" of the new "green" channel is General Motors [4], which makes gas-guzzling Hummer SUVs. Even with gas at $4 a gallon and Hummer's 32-gallon gas tank costing $128 to fill, GM still plans to roll out the largest Hummer yet this fall. The H3T is 22 inches longer than the H3, and has a four-door cab and an open truck bed. Thanks to plummeting Hummer sales and maybe also the obvious clash with its desire to be considered "green," GM is considering selling off the brand [5].
