Because there are probably more than five web companies left that haven't been eyed for acquisition, Google is reportedly in talks to acquire Yelp, the review site that has a big web and mobile presence in North America and the UK.
If it goes through for anywhere close to a rumoured $US500 million, Google will have spent $US1.5 billion on acquisitions since August, or roughly the same it spent on YouTube three years ago.
At this point, the question is more about what companies haven't been acquired by Google, despite seeming like perfect matches. Any web services or software makers out there you can't believe haven't shown up on the big G's radar? NYTimes.com, MediaMemo]
