On the last day of the year, Walt Disney Co. and NBCUniversal Media LLC each signed new deals with cable carriers that avoid year-end blackouts, and AMC Networks agreed to a temporary extension of its contract with another carrier.

Burbank-based Disney on Monday said it entered into a long-term agreement with St. Louis-based Charter Communications, the nation’s fourth largest cable operator, to carry up to 70 different Disney networks, including ESPN, Disney Channel and the upcoming ABC News/Univision news network.

Also, New York-based NBCUniversal, which has operations in Universal City, and the National Cable Television Cooperative signed an agreement that enables nearly 1,000 independent cable operators to carry the entire NBCU portfolio, including MSNBC, CNBC and Bravo.

In addition, AMC Networks and Time Warner Cable, the nation’s second largest cable operator and one of the largest operators in Southern California, continue to negotiate a long-term carriage deal renewal for the IFC and WE cable channels under a temporary contract extension.
