Yesterday, BoomTown went to Washington, D.C. to see lawyers from Microsoft (MSFT), Yahoo and Google face off in Senate hearings about the controversial search advertising outsourcing deal recently struck between Yahoo (YHOO) and Google (GOOG).

Titled “The Google-Yahoo Agreement and the Future of Internet Advertising,” the hearings were called by the Judiciary Committee’s Subcommittee on Antitrust, Competition Policy and Consumer Rights and chaired by Sen. Herb Kohl (D., Wis.).

As I expected, the hearings on the Yahoo agreement with Google (transcripts of testimonies here) to outsource some of its ad search business were a lot of show and not so much content.

There was also a hearing for the House’s Task Force on Competition Policy and Antitrust Laws, called “Competition on the Internet,” which featured the same trio of execs.

And here’s a video of BoomTown chatting up Google’s Chief Legal Officer David Drummond, Microsoft’s General Counsel Brad Smith and Michael Callahan, general counsel for Yahoo, right after the Senate hearings were over.

Please see this disclosure related to me and Google.
