RPM 
            Birthdays 
            and Unbirthdays
          

           
          Phonographians 
            find many days and many ways to Celebrate the Phonograph!
           
            
          
          
 
            Phonograph records have revolved at many 
            speeds, most of which have come and gone. 
          Record speeds are, however, 
            one way to remember the Phonograph. 
          There are currently 
            seven Friends of the Phonograph "RPM 
            Birthdays".
          These RMP 
            birthdays are an opportunity to "tip your cap" to the history 
            of phonograph RPMs and doing so as part of a Friend of the Phonograph's 
            birthday celebration.
          These "tip 
            of the hat" RPM birthdays are based on the phonograph record 
            speeds of "8 1/3" 
             , 16 2/3" , "33 
            1/3" , "45" , "78" 
            , "80" , "90" 
            (1)
          If you 
            are a Phonographian 
            and your birthday age is one of those RPM speeds you should give the 
            phonograph a tip of the hat as part of your RPM birthday celebration.
           
           
              
          
 
          
 
            
 
            
           
          
           
          Obviously invented by a 
            Phonographian, an RPM birthday is an addendum to a birthday. As such, 
            it's an opportunity for Phonographian's to mention the phonograph 
            and explain phonograph RPMs to all in attendance (something that only 
            a guest, celebrating your birthday, would probably listen to with 
            a smile). 
           
        
        
 
          
           
          If 
            it isn't an RPM Phonographia Birthday or Phonographia 
            Red-Letter Day, it can still be celebrated!
          Friends 
            of the Phonograph look for any excuse to 
            celebrate connections with the Phonograph. 
          Lacking 
            an RPM Birthday, a Phonographia Red-Letter Day, or a Friend of the 
            Phonograph's Birthday there are many other Phonographia On This 
            Day events that can be celebrated. 
          Check the 
            Phonographia On 
            this Day Calendar for what happened today related to the phonograph's 
            history. 
          Nothing on any calendar? 
            Then simply remember that a Phonograph's Unbirthday 
            can always be celebrated.

          (1) - The 
            celebration of the phonograph's RPMs - Although early disc and cylinder 
            recordings were produced in a variety of speeds ranging from 60 to 
            160 RPM, FOTP Red Letter RPM Birthdays are currently the following: 
             
           
             
              8 1/3 RPM 
                (used by the National 
                Library Services starting in "1969 to record magzines 
                and the recording of all disc talking books at 8-1/3 rpm began 
                in January 1973. Use of these slow recording speeds made it possible 
                to include almost twice as much material as on a disc of corresponding 
                size recorded at 16-2/3 rpm.
              16 2/3 RPM 
                (first used in early 1930's and subsequently used for 1) spoken 
                word recordings, 2) car music systems like Chrysler's Hi-Way Hi-Fi 
                2 of the 1950's 3) background music systems for restaurants and 
                businesses 4) limited music formats - see Canada Antique Phonograph 
                Society (CAPS) May 2010 article by Mike Dicecco for history of 
                16 2/3 format); 
            
           
           
            33 
              1/3 RPM (first used by Vitaphone in 1930 for electrical transcription 
              recordings and introduced in 1948 by Columbia Records as the Long-Playing 
              Record (LP)); 
            45 
              RPM  (introduced by RCA in 1949); For a brief history of the 
              45 rpm go to Historys

              RPM  (the standard for early disc records from 1890s into the 
              1950's); 
            80 
              RPM  (for Edison Diamond Disc records), 
            90 
              RPM (for Pathé disc records with vertically cut grooves requiring 
              a special sapphire ball-shaped stylus).
