When he started in 2008, David Sparling worked out of a small office, not far from a six-seat, nine-computer laboratory, with the largest computer at the time being an iMac with about one gigabyte of memory. There was a decades-old practice room building with fewer than a dozen rooms, showing obvious signs of age, recalled Sparling, a Southeastern University assistant professor of broadcasting. Today, a state-of-the-art Mac lab has room for 30 students who have access to 28 16-gigabyte computers — the fastest processor currently available.
