Nielsen IAG will tell you how well your TV advertisement reached its target audience. The company provides advertising performance measurement services clients that include American Express, Toyota, Verizon, NBC Television, and CBS. The firm monitors the effectiveness of television commercials, product placement campaigns, and commercial sponsorships by conducting more than 100,000 surveys daily about the programs the consumers watched the night before. Nielsen IAG also measures the effectiveness of in-theatre and movie ads in a television campaign. In May 2008, the former IAG Research was acquired by marketing and media information giant Nielsen; it changed its name at that time.
