In the mid 1950s through the early 1980s, a telephone busy signal provided an early form of [[social media]] in many cities and towns of the United States, colloquially known as the "[[beep line]]" or "jam line".<ref>{{cite web|url=https://www.mprnews.org/story/2012/12/24/arts/jam-line/|title=Jam Line: Remembering a Twin Cities teen phenomenon|first=Sasha|last=Aslanian}}</ref><ref>{{cite web|url=http://www.vintagerotaryphones.com/the-beep-beep-line-the-jam-line-busy-signal-chats/|title=The Beep-Beep Line- The Jam Line – Busy Signal Chats - Vintage Rotary Phones|first=David W.|last=Zemens|website=www.vintagerotaryphones.com}}</ref> Due to a flaw in the telephone switching equipment, teenagers discovered they could talk to each other over the busy signal, often exchanging phone numbers, mostly for the purpose of [[dating]]. Common phone numbers for this to form were on popular [[Radio broadcasting#Types|radio station]] request lines, where teens would be calling in en masse to try to win concert tickets or request their favorite songs, thus "jamming the lines" and generating a perpetual busy signal.
