The Hot Spot Connection site was designed from the ground up using Flash to create the ultimate engaging user experience. Special attention was paid to maintaining usability and maximizing ad space revenue. Visitor engagement hooks were added in the form of free content brokered via RSS feeds from People, Sports Illustrated and various other A-level publications. A sophisticated ad and content caching server had to be engineered to work around technical firewall problems that had plagued previous projects. The ad server allowed for personalized ads based on demographics and location. The system was also designed to support an array of campaigns to promote AT&T Wi-Fi and other services.
