York experienced great changes following World War II. People began moving from the city to the suburbs, and many department stores, like Bear's, Wiest's, Jack's, and Gregory's, closed. Long-standing companies such as AMF and York Air Conditioning were sold or moved, while banks, industries, and businesses merged. The York County Shopping Center opened on the East End, attracting customers who had formerly shopped downtown. WSBA TV went on the air in 1952, starting a new era in communication and a business empire that still has a strong presence today. The band Live grew from a group of local high school students to well-known musicians that graced the cover of Rolling Stone. Jeff Koons became one of the most celebrated artists in the world, Kim Bracey became the first African American mayor, and York businessman Tom Wolf became governor. York continues to celebrate its rich heritage as the "Factory Capital of the World.
