Brighton based Harris Interactive announced Nielsen Holdings is buying the company for $117 million.
The Board of Directors approved the deal, which includes Nielsen acquiring all of Harris' outstanding shares of common stock.
Shareholders will receive $2 per share in cash.
Harris' president and CEO AL Angrisani said in a statement: "This announcement reflects the successful completion of the turnaround strategy that we began in July 2011 and will deliver to Harris Interactive stockholders meaningful value and liquidity immediately upon closing."
Nielsen's President said, "Harris Interactive would complement Nielsen’s existing capabilities, enabling deeper insights for existing CPG and media clients, and growth opportunities in other industry sectors."
If approved under certain conditions, the deal is expected to close in the first quarter of 2014.
