Can Google still innovate?

BBC News:

"Despite the ventures into new areas - the Chrome web browser, voice-activated search, Android - Google still lives and dies by the quality of its search engine. Matt Cutts told me 400 adjustments to search had been made last year. I'm sure the people over at the "moneyplex", watching anxiously to see whether the growth in online advertising spending falters, remind their colleagues daily of the need to keep focussed on the core business which has proved such a huge money-spinner."

The story is too old to be commented.
