    Federal Communications Commission FCC 12-81 to grant retransmission consent or the right to mandatory carriage.149 If a station elects retransmission consent, the broadcaster and an MVPD negotiate a carriage agreement, which may include monetary or other types of compensation in return for the right to carry the broadcast signal. 150 Where a station elects must carry, it is generally entitled to carriage but it is prohibited from receiving compensation.lSl Qualified local noncommercial educational ("NCE") stations have a right to mandatory carriage within the same must-carry market, but do not have retransmission consent rights.152 Cable operators also are permitted to negotiate for retransmission consent with any other broadcast station they seek to carry irrespective of the station's television market. 153 58. In recent years, some MVPDs' and broadcasters' negotiations have resulted in public retransmission consent disputes, leading a coalition of MVPDs and consumer groups to file a rulemaking petition with the Commission in 2010.154 The petitioners argue that the Commission's retransmission consent regulations are outdated and harmful to consumers.155 The Commission issued a Notice of Proposed Rulemaking in 2011 seeking comment on several proposed revisions to its retransmission consent regime. 156 Among other things, the Commission sought comment on modifying the good faith negotiation standards to include additional negotiation violations, revising the "totality of the circumstances" standard used to determine whether actions in
