Camp and Stumbleupon are on a roll of reaching milestones. They recently set a new record with 27.5 million stumbles in one day and also surpassed Facebook to become the number one website for generating social media traffic in the U.S, accounting for 43.34% of the market. The company was briefly owned by ebay from 2007 til 2009 when Camp sold and re-bought the company. And with his return Camp is taking it from strength to strength.
