Is Radio Drama (In The United States) Dead?

I recently received from HarperCollins a review copy of a paperback psychological thriller called The House on the Cliff by Charlotte Williams, a British author. The one thing that struck me was her back page bio which noted that Williams "works in radio drama, writing original plays and adaptations."

I love radio drama.It has for a long time been known as the "theatre of the mind" because it allows listeners to use their imaginations as they gather around their radios. Unfortunately, radio drama is a dying art in the United States. I hope some enterprising radio producer or broadcast station will make an attempt to revive it. The late radio producer Himan Brown in the 1970s tried to with the CBS Radio Mystery Theatre but failed. That was probably because the productions were too much of a throwback to radio as it was done in the 1930s and '40s rather than doing something innovative or experimental.
