However, following many years in the corporate world, I feel that the time is right to take a step back and focus more on my personal and family obligations. I have had a long and satisfying association with Arbitron and through that time, have developed a deep respect for Steve Morris and the other members of the management team, as well as for my fellow directors. I look forward to working with the Board until my retirement and have the utmost confidence that this talented team has the skill and strength necessary to move forward in a way that benefits all of its constituencies.”

Steve Morris, president and chief executive officer of Arbitron, added, “On behalf of the entire Arbitron team, I would like to thank Larry for the countless contributions he has made during his time as Chairman. We will miss his valuable insight and guidance, but we understand and appreciate his need to take such a step and wish him the best as he moves on to this next phase in his life. Arbitron has been and continues to be a leader in sound corporate governance practices, and we will carefully review our options to ensure the best, most responsible Board structure going forward.
