What Happened to Intel's Pentium? Why a Hidden Flaw Cost $475 Million

In 1994, Intel released the Pentium, the most advanced consumer processor ever built at the time, and within months it was facing one of the most expensive product crises in tech history. A mathematics professor in Virginia noticed his calculations were coming out wrong, traced the problem back to the chip on his desk, and sent an email that eventually reached millions of people. What followed was a corporate response that turned a minor technical flaw into a four hundred and seventy five million dollar charge against a single quarter's earnings. This video breaks down exactly what went wrong inside the chip, why Intel's response made everything worse, and what the whole episode revealed about the relationship between a company and the customers who trusted its product.
