Blockbuster Passing on Netflix

Blockbuster turned down the chance to buy Netflix for $50 million in 2000 and later filed for bankruptcy in 2010, while Netflix grew into a $200 billion streaming giant. This decision underperforms Nokia's Smartphone Fumble on market capital loss, as Blockbuster forfeited a 4,000x return on its $50 million investment. At the time, Blockbuster dismissed Netflix’s DVD-by-mail model as a niche service, failing to see the shift to digital streaming. The $50 million they refused to spend would have become $200 billion, making this not just a missed opportunity but one of the largest value forfeitures in corporate history—a loss that dwarfs even the failed mergers on this list.
