PBS has picked up one series from Brandon Tartikoff’s Moving Target Prods. and passed on another, the service confirmed.Tartikoff’s “The Steven Banks Show,” featuring the improvisational comic, will premiere for a nine-week run July 11. However, the service has passed on “Under New Management,” a sitcom that was supposed to be built around topical issues. PBS officials said in a statement that, after developing 13 scripts, it was mutually agreed that “the program may be more suited to commercial broadcast outlets,” and that Tartikoff is free to shop it elsewhere. Both shows are in conjunction with New Orleans pubcaster WYES. Meeting in Alexandria, Va., PBS officials also gave the go-ahead to two new series: “Brainstorm,” a half-hour gameshow premiering next fall, which will be exec produced by Nancy Linde of WGBH/Boston’s science unit and “The Great War and the Shaping of Our Century,” an eight-hour series exploring military, political and cultural aspects of World War I, produced by Blaine Baggett (“The Astronomers”).
