The '94 Pan American Race Walk Cup this weekend is the first of 29 test events for ACOG. The competitions will "tell how ready ACOG's staff, volunteers, results, transportation, and countless other systems are" for the real show in '96 (Joe Drape, ATLANTA CONSTITUTION, 9/20). OLYMPICS BIZ IS BOOMING: Saturday's ATLANTA CONSTITUTION profiled ACOG. By the time the Games begin, ACOG will have 71,172 employees -- three times more than the work force of any GA-based corporation, even Delta and Coke. Women account for 60% of ACOG's staff and nearly 40% of management. About 37% of the staff and 18% of management are minorities (Melissa Turner, ATLANTA CONSTITUTION, 9/17). FIVE-RING NOTES: In BUSINESS WEEK, David Greising reports of McDonald's exclusive deal with the Olympics and NBC. Noting past "ambush" ads: "This time around, the sponsors aren't going to permit a repeat of this 'ambush advertising'" (BUSINESS WEEK, 9/26 issue).... BellSouth will be a sponsor in the telecommunications category, providing about $15M, mostly in products and services, to ACOG. The announcement is expected this week (CONSTITUTION, 9/17).
