Programming Language Popularity – Part Eight

I compiled some programming language popularity statistics in April 2009, October 2009, October 2010, September 2011, August 2012, Februrary 2013 and September 2013. Here’s an update for May 2014:

I made a number of Google searches of the forms below and summed the results:

"implemented in <language>"
"written in <language>"
"developed in <language>"
"programmed in <language>"

I’ve divided the table into sections based on large percentage drops from one language to the next.
