The chief executive of media research firm Arbitron Inc. has resigned amid allegations that he provided false testimony to a congressional committee. The Columbia-based company said in a statement this week that Michael P. Skarzynski resigned because he had violated a company policy in a matter "entirely unrelated" to financial performance. U.S. Rep. Edolphus Towns, chairman of the Committee on Oversight and Government Reform, said in a statement that Skarzynski might have provided false testimony during a December hearing about whether Arbitron's people meter would silence minority radio stations. Skarzynski is being replaced by William T. Kerr, who has been a director at Arbitron since 2007.
