This system enables the sales staff to book sales orders and print a log that tells the people in master control which commercials to air and when. That log also is produced in electronic format and fed into the library management system that stores all the actively running commercials. The library management system automatically makes the commercials run at the scheduled time and produces a list to alert master control of spots that are scheduled to run but which are not stored in the system. Using one traffic system for multiple countries has its share of challenges. Each country handles promotions and the numbering of commercial spots differently.
Government regulations differ greatly, especially regarding children's programming.
Turner also faced challenges in connectivity. When Turner's international traffic system was first implemented, it was designed for single stations in the same building. However, at least 50 people at CNN Center needed to access the system. In the three years since, Turner has continued to use SNA Server, upgrading as new versions have become available. While the number of users has grown, and more sites have been added, administration for those now 200 users still requires only one person.
