As the open source git distributed version-control system celebrates its 15-year anniversary next week, it is hard for us to remember that developers used to rely on other types of version control systems. Let’s take a brief stroll down memory lane from git’s early days, to its tipping point and now its consolidation phase.

According to a 2007 survey of git users, 80% had experience using Subversion (SVN) and 69% had used CVS (concurrent versions system). These early fans of git were still the minority of developers. In 2009, a survey of the Eclipse community, which originated from a Java IDE (independent development environment), SVN was the primary source code management system for 58% of respondents, while only 2% used Git or GitHub. After this point, git continued to gain strength.

Git surpassed “open source” search queries in March 2011. Two months later,  GitHub moved past Sourceforge in terms of commits made in the first half of that year. 2012 saw Andreessen Horowitz make a big investment. Over the next seven years, GitHub code repositories went from 27% to 70% of the open source projected indexed in the Synopsys/Black Duck Open Hub. By the time 2014 arrived, Git surpassed SVN as the primary code management tool in Eclipse’s annual survey.

Git jumped to another level of dominance sometime in 2018 or 2019 — basically when Microsoft bought GitHub. For example, StackOverflow’s surveys show a jump, with git use going from 69% in 2015 to 87% in 2018. Subversion is the clear loser in terms of version control used by developers, going from 37% to 16% over the same time period. JetBrains and SmartBear surveys found similar changes in the 2018 to 2019 time period.

Why was git’s rise so dramatic, and what are the implications of its current dominance? Some answers can be found in InApps Technology’s roundtable discussion with Jason Warner, GitHub’s CTO Jason Warner, Weaveworks CTO Cornelia Davis, and GitLab CEO Sid Sijbrandij.
