Editing Murray Hill, Manhattan (section)

==Telephone exchange==
For the most part of the 20th century the name "Murray Hill" was used by [[New York Telephone]] as a [[Telephone exchange name|telephone exchange]] for residents living on the [[East Side of Manhattan]], served from the East 37th Street exchange building. Though the entire city was covered by [[area code 212]] until the 1980s, most neighborhoods at the time would be grouped together by a particular exchange name. Other municipalities in the United States would also use MUrray or MUrray Hill as an exchange name. The first two letters in MUrray (capitalized to indicate that they should be dialed) would be followed by five digits to make up a telephone number, such as MUrray Hill 5-9975 (the Ricardos' number on ''[[I Love Lucy]]'').<ref>{{cite book |last=Small |first=Cathleen |year=2017 |url=https://books.google.com/books?id=MJRmDwAAQBAJ&pg=PA15 |title=American Life and Communication from the Telephone to Twitter |location=New York |publisher=Cavendish Square Publishing |isbn=9781502619778 |page=15 |access-date=February 20, 2025 |via=Google Books}}</ref> This was the way most [[telephone number]]s were given until [[AT&T Corporation|AT&T]] switched to [[all-number calling]] by the late 1970s to early 1980s. Nevertheless, the name MUrray Hill is still applicable, as many East Side phone numbers in area code 212 still begin with 68, which corresponds to MU on the [[telephone keypad]].
