In all fairness to Google's attempts to look like an innovator by acquiring, copying, or hijacking innovations from others...pick any tech giant, they're all like that. Microsoft has always been primarily an acquisition company also, starting with MS-DOS, bought from Seattle Computer Products as 86-DOS. Microsoft's own products were often mediocre at best - Publisher, anyone? As for Apple, after the IIe generation, they "innovated" the Mac by copying the mouse and GUI concepts originally developed at Xerox PARC, already deployed by Sun Microsystems for one. Mac OSX is built on a fork of FreeBSD, and was acquired by buying NeXT, which had been developing it for some years.

Most of our most fundamental "innovations" in hardware and software have originally come either from research contexts like Xerox PARC, or from small upstart companies long ago swallowed up by the big acquirers.
