My understanding is that in the 1980s and perhaps in the 1990s, too - Pascal and C were pretty much head-to-head as production languages.

Is the ultimate demise of Pascal only due to Borland's neglection of Delphi? Or was there more of such bad luck; or perhaps something inherently wrong with Pascal (any hopes for its revival?).

I hope it's not an open, unanswerable question. I'm interested in historical facts and observations one can back up, rather than likes and dislikes. I also failed to find a duplicate question, which actually surprised me somewhat.
