Besides the TIOBE Index, which ranks programming language popularity by search engine hits and seems to have data reaching back to the year 2001, are there other sources with some form of measure for the popularity of programming languages in the last millennium?

    FWIW, the "Very Long Term History" section on that page has some information going back to 1989. (C, C++, and LISP were apparently the big three.) So that site may have information that they're not presenting in detail. – fadden Jun 8 at 20:23
  • Define 'popularity' – Bruce Abbott Jun 10 at 2:14
  • Asking 'for some form of measure' I meant to keep this as general as possible knowing how vague the term 'popularity' is but also how hard it might be to find any pre-WWW data at all: number of usenet questions, number of scientific articles stating a language being used... I have added an answer based on a search for number of library items: many books about Pascal and BASIC being published in the 80s 'rhymes' with my memory of these languages being very popular among hobby programmers at that time. – v-joe Jun 11 at 1:37

    I wonder if maybe Dr. Dobb's Journal might have done some surveys back in the day? – LAK Jun 13 at 14:46

Below is an attempt of ranking 'popularity' of programming languages invented in the 1980s or earlier by searching for "language programming" on worldcat. The table lists how many library items exist per year. C and C++, e.g., can unfortunately not be distinguished in this search, and there are also false positives, considering that C's first release year is 1972.

Graphing the top-eleven languages (by overall publications) per year gives:

    Added a graph of the top-eleven languages by year... hope that's OK. – TripeHound Jun 10 at 10:13

    The graph does add a nice overview. I'm surprised about Ada having such a high publication count. – v-joe Jun 10 at 10:24

    Very interesting. I see you have FoxPro in the list, but that didn't exist until 1994 (it was called 'FoxBase' before that). 'dBase' or 'xBase' might be worth including, though. – LAK Jun 10 at 19:44

    @MichaelShopsin "Assembler" might show more/better results: one might generically talk of "assembly language" but I have a feeling (from memory only) that books (especially processor-specific ones) might be more along the lines of "Programming in Z80 Assembler" etc. – TripeHound Jun 10 at 20:01
  • 1
    @LAK good catch, I've added dBASE to the list (FoxPro for DOS was indeed only introduced in 1989: foxprohistory.org/foxprotimeline.htm ). – v-joe Jun 11 at 1:28
