The Ann Arbor District Library reimagined its summer reading program by transforming it into an interactive scavenger hunt called the Summer Game, which utilizes Twilio Programmable SMS to engage the entire community, including children, teens, and adults. The program uses text messages to create a fun and inclusive experience, allowing participants to interact with each other and with the library through mobile communications. By leveraging this technology, the library has seen significant growth in participation, with over 16,000 residents participating annually, and received high praise from the community, earning an 89% approval rating in a recent public opinion poll. The Summer Game has become one of the most popular summer events in Ann Arbor, driving community engagement and fostering emotional investment among participants.
