Ad Age reports that Google sales exec Tim Armstrong “is calling for a town hall meeting with the Association of National Advertisers.” [sub. may be required]. The ad association has come out against the proposed Google/Yahoo search ad combine. But such a meeting shouldn’t be a closed door `only the ad biz’ event. By now, Google’s key execs should recognize that the search and online ad market is connected to such issues as privacy, the state of competition, and the future of funding diverse content online. This isn’t an issue that should be constructed by Google as an insider deal. The full range of public policy issues must be debated–including the participation of independent advocates and academic experts to discuss privacy and related concerns. Let Google, the advertisers, critics, supporters, and those in-between have their say–and make it available prominently on YouTube.
