52. Arbitron

The media and marketing research firm engages in several businesses. It measures network and local market radio audiences across the United States. It surveys the retail, media and product patterns of U.S. consumers. And it provides estimates and analytics for the fast-growing mobile phone and tablet world. In September, it announced a partnership with Reston-based ComScore to measure consumption of video, audio and display content across radio, television, PCs, smartphones and tablets. In December, COO Sean R. Creamer was named to succeed president and chief executive William T. Kerr, who is retiring Jan. 1.

The audience measurement firm developed the Portable People Meter, a device that can detect hidden audio tones within a station or network's audio stream to determine what the wearer is listening to at any given time.
