Why “Zillow”?

Once they hatched their idea, they needed a name. “Zillow” evolved from the desire to make zillions of data points for homes accessible to everyone. But a home is about more than data - it is where you lay your head to rest at night, like a pillow. Thus, “Zillow” was born. They knew they had a winning name when employees began talking in Z-language and newly-minted words starting with “Z” popped up everywhere (e.g., Zestimateâ„¢, Zindexâ„¢).

But I guess I’ll have to add “Cab Calloway” there for “just plain gibberish” origin courtesy of Dr. Seuss?
