You have to think like Westinghouse back then, and earlier. The only reason they made appliances in the first place was to spread consumption of electricity. Their REAL business, and the last of theirs to die when they lost control of themselves in the 90s, was generation and distribution apparatus. Think of it as building vacation destinations because you owned an airline. OK, skewed analogy. But the more stuff they could make electricity do, the more generation and distribution machinery they could sell. That was the REALLY expensive stuff. It still is today. The electric supply is the most heavily capitalized industry in the world.
