I think you typed "yes" where you meant "no." Tech company R&D gave us things like the transistor and lasers (both from AT&T) and Mandelbrot fractals and hard drives and the entire concept of a relational database (all from IBM). PARC in specific gave us Ethernet, which I think is safe to describe as "being used in the real world." Google has a long way to go; so far, all of its real contributions have been in software, and all of their hardware R&D has seen very little "real world" deployment. Otherwise it's very much just a well-marketed implementation of traditional corporate R&D.
