1991
In 1991, he co-founded Ink Development, a pen-based computing startup that later was rebranded as an e-commerce company and renamed eShop Inc.
1995
In 1995, at 28, Omidyar began to write the original computer code for an online venue to enable the listing of a direct person-to-person auction for collectible items.
He created a simple prototype on his web page.
On Labor Day, Monday, September 4, 1995, he launched an online service called Auction Web, which would eventually be developed as the auction site eBay.
The service was originally one of several items on Omidyar's website eBay.com.
His website also had a section devoted to the Ebola virus, among other topics.
The first item sold on the eBay site was a broken laser pointer.
Omidyar was astonished that anyone would pay for a broken device, but the buyer assured him that he was deliberately collecting broken laser pointers.
Similar surprises followed.
The business exploded as correspondents began registering trade goods of an unimaginable variety.
Omidyar incorporated the enterprise; his small fee on each sale financed the site's expansion.
The revenue soon outstripped his salary at General Magic and nine months later, Omidyar decided to dedicate his full attention to his new enterprise.
