General Managers may have different functions in different organizations but a common thread is that they manage player rosters and personnel and are responsible for the draft. Insulated by assistant GMs and advisors, a scouting department, MLB and Minor League coaching staffs and now, a baseball operations department filled with data science analysts, the GM is like a baseball conductor. To complicate his life more, he must also answer to a President and Owner. The GM role exists in all major sports and has been around in baseball for quite some time.
The nature of the GM has changed over the years as well, shifting from a more experienced baseball-guy to Ivy League-educated analytically-minded whiz kids in their 30s or 40s.
As far as data capture on General Managers, we only have GMs for the Major Leagues as Minor League Gms are mostly business managers and are not responsible for the same tasks as MLB GMs. We have date of hire and fire for GMs since the 1950s and each GM will have their own page.
