At the turn of the century, Blockbuster reigned supreme in the video rental industry. If your family craved a movie night, someone likely had to drive to one of Blockbuster's 9,000 stores, stroll through rows of DVD-lined shelves, and hand a membership card to a blue-clad employee. When Reed Hastings, founder of a fledgling startup called Netflix, met with Blockbuster CEO John Antioco in 2000 to propose a partnership, he was laughed out of the office.

Only 10 years later, Netflix became the largest source of streaming Internet traffic in North America during peak hours, with over 20 million subscribers. Blockbuster declared bankruptcy.
