Using the telephone with poetic license.

Dial-A-Poem began at the Architectural League of New York in January 1969 with 10 telephone lines and ran for 5 months, during which time 1,112,337 calls were received. It continuted at MOMA in July 1970 with 12 telephone lines and ran for 2 and a half months and 200,087 calls were received. It was at The Musuem of Contemporary Art, Chicago for 6 weeks in November 1969 and since then has cropped up everywhere. This was with equipment working at maximum capacity and sometimes jamming the entire exchange. At MOMA, the 12 lines were each connected to an automatic answering set, which holds a pre-recorded message. Someone calling got randomly one of 12 different poems, which were changed daily. There were around 700 selections of 55 poets.
