The parties again have set a new deadline to settle their retransmission consent battle: This time it’s 5PM ET on Monday. The fight involves CBS-owned stations that reach some 3.5M Time Warner Cable homes, primarily in New York, Los Angeles and Dallas. The No. 1 broadcast network wants extract a big retrans price increase, and the companies’ current carriage deal was set to expire tonight. In a memo to staffers yesterday, CBS chief Leslie Moonves wrote that there’s “a very real threat” that the blackout will happen and “possibly” also affect Showtime. Last week, both companies set up competing websites to defend their cases in the dispute.
