According to an application filed with the FCC this week, Radio Disney station WRDZ/Chicago has been sold to Chicago media company Polnet Communications for $3,450,000. This will be Polnet's fifth AM station in the Chicago market, with four others in the northern suburbs. Polnet also owns a television station in the market. William B. Schutz and Kozacko Media Services served as the brokers in this transaction, which is pending FCC approval.
