 The shows are created using techniques from the 1950s (including home-made sound effects) and are broadcast across the U.S. and around the world by thousands of radio stations.Today, radio performers of the past appear at conventions that feature re-creations of classic shows, as well as music, memorabilia and historical panels.The largest of these events was the Friends of Old Time Radio Convention, held in Newark, New Jersey which held its final convention in October 2011 after 36 years.
