Hitachi does it.
Printers, power tools, nail guns and nails, aircraft engines, car engine management systems, storage systems, dump trucks, excavators, involved in nuclear power, medical equipment, elevators, air conditioners, washing machines, batteries and many other totally unrelated things.
Imagine if they had a single 1800 number, tech support, and a bundling program.
By a dump truck and an escalator and get a reduced price on a 1PB SAN! Total convergence and bundling that Verizon or ATT could never even dream of!
