Part adventure, part history lesson, and part treasure hunt, eight-time Emmy® Award-nominated ANTIQUES ROADSHOW marks its 15th season in 2010. PBS's highest-rated series, ROADSHOW is seen by almost 10 million viewers each week. Veteran television personality Mark L. Walberg serves as series host. In each hour-long ROADSHOW episode, specialists from the country's leading auction houses—Bonhams and Butterfields, Christie's, Doyle New York, Skinner and Sotheby's—and independent dealers from across the nation offer free appraisals of antiques and collectibles. ANTIQUES ROADSHOW cameras capture tales of family heirlooms, yard sale bargains and long-lost items salvaged from attics and basements, while experts reveal the fascinating truths about these finds.

For decades, the Rockefeller name was despised in America— associated with John D. Rockefeller Sr.’s feared monopoly, Standard Oil. The world’s first billionaire, Rockefeller held 90 percent of the world’s oil refineries, 90 percent of the marketing of oil and a third of all the oil wells. Working methodically and secretly, he transformed an industry—and changed forever the way America did business. Though Rockefeller’s only son dedicated his life to redeeming the family reputation, and Rockefeller had given away half his fortune by the end of his life, his philanthropy couldn’t erase the memory of his predatory business practices.

Florida’s Everglades National Park is one of the last great wildlife refuges in the United States, home to numerous unique and endangered mammals, trees, plants, birds and turtles, as well as half a million alligators. However, the Everglades is also the dumping ground for many animal invaders over 15 species of parrot, 75 kinds of fish and 30 different reptiles from places as far away as Africa, Asia and the Caribbean. All of the intruders found their way into the park either by accidental escape from pet owners or intentional releases by people no longer wishing to care for an exotic species. Add to the mix tens of thousands of giant pythons, snakes that can grow to 20 feet and weigh nearly 300 pounds, some released into the wild by irresponsible pet owners, some escapees from almost 200 wildlife facilities destroyed by Hurricane Andrew in 1992. The predatory pythons slithered into this protected wilderness and thrived, and the refuge has consequently become less of a haven and more of a killing ground every day since then.

In a television landscape populated by countless iterations of CSI and its ilk—crime dramas where the emphasis is on forensics as crime-solving technology rather than in old school policing—Masterpiece Mystery’s delightful Inspector Lewis may feel like an odd man out. But in the case of Lewis, which returns to PBS on Sunday for a fifth season (or sixth, if you’re going by the U.K.’s numbering system), that’s a good thing indeed.
