He owns two professional sports teams: the Seattle Seahawks of the National Football League They also used the laboratory of the Computer Science Department of the University of Washington; on at least one occasion in 1971 they were banned from the laboratory for abuse of their privileges there.
Allen later convinced Gates to drop out of Harvard University in order to create Microsoft.
Gates explained his official status with Harvard that, "...
If things [Microsoft] hadn't worked out, I could always go back to school.
I was officially on [a] leave [of absence]." In 1980, after promising to deliver IBM a Disk Operating System (DOS) they had not yet developed for the Intel 8088-based IBM PC, Allen spearheaded a deal for Microsoft to purchase a Quick and Dirty Operating System (QDOS) which was written by Tim Paterson who, at the time, was employed at Seattle Computer Products.
As a result of this transaction, Microsoft was able to secure a contract to supply the DOS that would eventually run on IBM's PC line.
This contract with IBM was the watershed in Microsoft history that led to Allen's and Gates' wealth and success.
Allen officially resigned from his position on the Microsoft board of directors in November 2000 but was asked to consult as a senior strategy advisor to the company's executives and still owns a reported 100 million shares.
Instead, Gates tried to buy Allen out at a low price to continue his ascension to the top.
