Showtime is teaming up with MSOs to help them sell phone service. Cox and Comcast are running various promos offering free or discounted Showtime programming when a consumer signs up for voice in select markets. One of the richer promos featured an entire free year of Showtime. More common are 3-month and 6-month offers, said Showtime vp, distributor marketing Laura Palmer. Time Warner Cable’s corporate office signed up to allow its divisions to run the Showtime-phone promo in 4Q. A recent telemarketing case study found response rates increased by 50% when subs received free Showtime and Movie Channel offers during phone signups, Palmer said.
