The first primary logo for the Spurs was introduced shortly after their founding, particularly in relation to the San Antonio Spurs Alternate logo. It featured a white basketball with black trim inside a red circle with "San Antonio" written at its top and "Spurs" written below it. This design remained unchanged until 1973 when green was added to give it more color contrast against other teams' logos on the court during games. In 1979, this original design underwent another change; this time featuring an updated font style for both words within the circle as well as changing from black to silver trim around the basketball itself.

In 1989, yet another new primary logo was unveiled by the San Antonio Spurs organization which is still used today: A silver spur outlined in black set against a blue background with white stars surrounding it along with “SAN ANTONIO” lettering above while “SPURS” lettering below - giving them the signature look they have become known for over past 30+ years now! This modernized version also features subtle shading effects between different colors making up the overall image more aesthetically pleasing than previous designs before being adopted officially in the 1990 season onward becoming synonymous not only with the city but the entire NBA league ever since then!
