What year was the ATX form factor originally introduced?

The ATX form factor was originally introduced in 1995 by Intel. This specification brought significant changes to motherboards and PC case designs, including optimizing power distribution and improving air flow for cooling. The introduction of the ATX form factor not only established standard dimensions for motherboards, allowing for better compatibility across various components, but also marked a shift in design philosophy towards modularity and improved thermal management, which are critical aspects in building modern computer systems. The specifications laid out by the ATX standard have had a lasting impact on the way PCs are built and have influenced subsequent form factors as well.
