John Malone, chairman of Liberty Media Corp., resigned from the board of Cablevision Systems Corp. to avoid conflicts that might arise because both companies own TV programming assets.
Cablevision, the biggest cable operator in the New York area, owns channels including AMC and Fuse, while Liberty has a stake in the Discovery Channel.
Malone resigned Monday, Cablevision reported Wednesday in a filing with the Securities and Exchange Commission.
Malone, who joined the board while Cablevision chair Charles Dolan battled to keep alive the Voom satellite TV service, is departing two months after the unit halted service. Malone in March said he joined Cablevision’s board because of his 40-year friendship with Dolan.
Cablevision spokesman Charles Schueler declined to comment beyond the filing.
