Uh no. Xerox made billions from the laser printer. And yes they missed capturing all the profit but it was crazy profitable. https://www.forbes.com/sites/gregsatell/2015/03/21/how-parc-...
Still, it shows my point, that research that reaches too far from the company’s core biz is difficult to recognize as a success. The laser printer, was a better printer and it was an improvement to Xerox existing scan+print business.
Bell Labs also had a lot of commercial success.
