Consumer research firm Nielsen reported a 15% jump in second-quarter revenue before the bell Tuesday. On the topline, the company reported $1.6 billion in sales driven by a 28% increase in media and digital audiences data and 6.6% in data on consumer purchasing patterns. Nielsen earned an adjusted 62 cents a share over its June-ended quarter, a penny over analysts' estimates and higher than 49 cents a share a year earlier. Including one-time charges, though, the company posted profits of 19 cents a share, far below $1.12 a share in the year-ago quarter. The decrease was due to recent refinancing of its long-term debt obligations. TheStreet's Keris Lahiff has details from New York.
