WaPo forgot to also blame the 1996 Telecommunications Act, which relaxed media ownership rules and have pushed noncommercial music almost entirely off the dial. WETA going all-talk is just the latest instance of jazz and classical genres being hushed. All the more reason for Congress and the FCC to expand Low Power FM licenses, so that symphonies and jazz organizations can get themselves back on the air. There was a study by the Knight Foundation that found radio is the most imortant indicator for a classical or jazz outfit's success (not unlike all forms of music, I suppose).
Let's all hope Congress passes the new LPFM legislation.
