Roosevelts ratchets PBS' ratings to highest since '94

Ken Burns' series The Roosevelts earned PBS its biggest audience in two decades, making it the documentary maker's third most popular film after The Civil War and Lewis & Clark: The Journey of the Corps of Discovery.

PBS says the seven two-hour episodes that aired last month had an average audience of 9.2 million viewers. The most popular was the first night, on Sept 14, which had 11.7 million viewers, according to the Nielsen company.

"It was power. It was sex. It was death. It was betrayal," says PBS chief programming executive Beth Hoppe.
