In 1998, Pierre and co-founder Jeff Skoll brought in Meg Whitman to help the business succeed. In 2002 the firm purchased IBazar and PayPal, and has since acquired and sold several others. 2008 marked the worldwide expansion of eBay. The company has entered into partnerships with several firms such as GM, Disney and Sun. The firm still operates today out of its headquarters in San Jose, California.
