Dell Computer Corporation
After graduating high school, he attended the University of Texas at Austin intending to become a physician. While at the university, he started a computer company called PC's Limited in his room in Dobie Center in 1984 with just $1,000 and an idea to provide affordable personal computers to college students.
The company became successful enough that, with the help of an additional loan from his grandparents, Dell dropped out of college at the age of 19 to run the business full-time. In 1987, PC's Limited changed its name to Dell Computer Corporation. Over time, and despite a number of setbacks (including laptops that caught on fire in 1993, temporarily losing the consumer market to Gateway in the mid 1990's, and others), Dell survived to become the most profitable PC manufacturer in the world, with sales of US$ 49 billion and profits of US$ 3 billion in 2004. In 2003, shareholders voted to rename the corporation Dell, Inc., in order to acknowledge Dell's prospective and ongoing product line expansion.
On March 4, 2004, he stepped down as CEO of Dell but stayed as chairman of the board, while Kevin Rollins, then president and COO, became president and CEO.
