Hadoop didn't come from Google, it came from more like Yahoo, who wanted an open source clone of Google's mapreduce framework. (Yahoo was paying Doug's salary, at least). MapReduce was deprecated inside Google several years ago in favor of Flume (think "apache beam" in the open source world). I point this out because google has had a lot of innovations that aren't necessarily now _products_.
