openhub.net (formerly ohloh.net) has an interesting comparison of the

market share between Bazaar, CVS, Git, Mercurial and Subversion.
I've been monitoring this since 2014-08-05 to see how things were
developing, and it's a good indication of the popularity of the various
version control systems.
I've created a repository at
<https://github.com/sunny256/openhub-repositories> where the project
scripts and data files are stored, along with graphs in SVG format.
The graphs are pretty interesting:

Graphs of relative growth between the various version control systems.

Zoomed-in version of relative.svg. Git goes through the ceiling.

Total number of repositories.
number of repositories is an interesting datapoint, but activity in the repos
would be far more interesting. There are a lot of repos of various types out
there that haven't been touched for years.
