MarketingVOX's parent firm Watershed Publishing early this morning launched an online trade magazine geared to media buyer/planners in all media. The MediaBuyerPlanner.com site has an editorial staff of four and will publish a daily email newsletter starting on Bastille Day (July 14).

MarketingVOX and MediaBuyerPlanner.com will share some content, particularly stories on interactive media, one of six major media sections in the new trade publication.

The site is ad supported, geared to advertisers such as publishers and broadcast networks, which often seek to reach media choice decision makers.
