StubHub
StubHub (often styled StubHub!) is an online marketplace owned by eBay, which provides services for buyers and sellers of tickets for sports, concerts, theater and other live entertainment events. It has grown from the largest secondary-market ticket marketplace in the United States into the world's largest ticket marketplace by a considerable margin. While the company does not currently disclose its financials, it is said to process one sports or entertainment ticket every second and in 2015 had over 16 million unique visitors and nearly 10 million live events per month.
