Since the mid-20th century, other student-run groups in music, theater and dance have proliferated and continue to flourish. In 2007 the University launched a campus-wide arts initiative to make the creative and performing arts central to the Princeton experience. The Lewis Center for the Arts, established the same year, has unified and strengthened the University’s many distinguished arts programs. Today, more students are participating in the arts, and at more advanced levels, than ever before.
