The company acquired a number of young companies that focused on network switches, such as the inventor of the first Ethernet switch Kalpana, and as a result Cisco switches did not run the IOS. When IOS was developed, Cisco Systems' main product line were routers. Through modular extensions IOS has been adapted to increasing hardware capabilities and new networking protocols.
