In 2013, Beyonc released an entire album without warning; three days later, it had sold more than 828,000 copies and changed how artists released music. The self-titled album arrived on iTunes at midnight on December 13, 2013. Its release skipped months of promotion, radio campaigns and retail leaks. A Harvard Business School case study later examined how Beyonc and Parkwood planned and produced the project.
