After years of watching their subscriber base give way to a generation of cord cutters, 2015 brought welcome news for cable companies. A new study by Monteray, CA-based research group SNL Kagan found that last year marked the best year in subscriber retention rates since 2007. But, research analyst Tony Lenoir cautioned, that’s not necessarily a sign that things are on the upswing for traditional cable. Rather, he said, it could just be a case of the “dead cat bounce” — a colorful term referring to a small, momentary rebound in performance that never leads to a full recovery.
