It has had ads for some time. Once (3-4 weeks back) I asked it a question about a particular event, and it showed me where could I buy related products below the response. That particular response was a bit badly formatted in json though. I suspect due to some Bing app bug it spilled the ads from the json in the response. So the ads were being sent to the client but not getting displayed I guess. The photo in the post shows the ad nicely formatted.
