Before version control systems, developers shared code manually—zipping files, copying to USB drives, and handing them off. This created chaos: conflicting changes, no merge tools, and zero change tracking. Reverting bugs was impossible, and collaboration was slow and error-prone.

The breakthrough came in 1972 when Marc Rochkind built SCCS at Bell Labs, the first tool to manage source code changes systematically. It tracked who changed what, pioneering the core concepts that modern systems still use. This solved the manual exchange problem with automated history.

Today, Git dominates as the distributed version control standard, with platforms like GitHub, GitLab, and Bitbucket enabling seamless team collaboration. The shift from pendrives to commands transformed development from a fragile, manual process into a reliable, scalable workflow where teams can work asynchronously without fear of overwriting work.
