The potential sale of interactive ad serving giant Doubleclick, especially to Microsoft, should set off a serious investigation at the FTC. Both the Anti-trust and Consumer Protection divisions at the FTC need to examine such a deal. There has been distrubing consolidation of ownership and control within the interactive marketing technology industry over the last few years. We also are concerned about the implications to consumer privacy as Microsoft’s adCenter merges with Doubleclick’s considerable suite of products, such as DART.
