“Classic Arts Showcase” is the project of one Lloyd Rigler, who decided on his own in the early 90s that there should be more arts on television. He provides round-the-clock feeds of performances by artists “available free, by satellite, to PBS stations, educational and community access channels and other nonprofit broadcasters since 1994; it currently reaches an estimated 65 million homes.” But it’s free to all but Mr. Rigler – he’s plowed $50 million into the project without a hope of ever getting it back.
