+\begin{frame}{Early Days of Computing (1950s--1970s). SCCS}
   Before the development of dedicated version control systems, programmers used manual processes to manage changes. Early systems, like the Source Code Control System (SCCS), developed by Marc Rochkind at Bell Labs in 1972, were among the first tools created to automate version control. SCCS stored multiple versions of code and helped manage modifications through change sets, allowing programmers to revert to earlier versions if necessary.

   Centralized version control systems (CVCS) came to prominence during the 1980s. These systems required a single, central server where all files and version histories were stored. Developers had to be connected to this server to commit changes or retrieve updates.
