On April 21st I reported that ads were spotted in the More Places section of local results in Europe.
I suppose it was only a matter of time, but less than four months later they're now being spotted in the local three packs. This was first reported by Ryan Scollon from Bowlinghat.
I could not replicate this in U.S. search.
Have you seen any ads in the three pack? If so, which version of Google are you using?
