INPUT, the annual international conference for public television networks and producers, is under way this week in Sydney, Australia. Attending — and blogging — are South Carolina ETV’s Amy Shumaker, the U.S. INPUT national coordinator, and Betsy Newman, SCETV producer and assistant manager of U.S. INPUT. So far they’ve run into pubcasters including Moss Bresnahan, president of KCTS in Seattle; Ron Hull, special adviser to NET in Nebraska (“who has a new book about his life in public television coming out soon,” they note); and Judy Tam, e.v.p. and c.f.o.of ITVS, INPUT president. Here’s a look at the U.S. programming entries.
