An exhibit by the Telecommunications History Group at the downtown Denver library lets you interact with pieces of telecommunications history. Telegraph key pads, switchboards and dial telephones are all on hand. The exhibit, on display through Sept. 28, tells the history of telecommunications in Colorado. Jody Georgeson is executive director of the history group, and she talks with CPR's Ryan Warner. (Originally aired Aug. 4, 2011)
