Tennis.com, a unit of the Tennis Company, which owns Tennis Magazine and other properties, will partner with Rolex to promote the forthcoming Wimbledon series. Rolex will sponsor a free daily e-newsletter called Breakfast@Wimbledon that previews upcoming matches and summarizes the previous day's games. Besides getting ad units in the newsletter, Tennis.com will be adorned with a virtual Rolex watch set to Greenwich Mean Time. The effort runs through July 9.--Karl Greenberg
