A new streaming service by Discovery, Viacom, A+E Networks, AMC Networks, and Scripps

People who are tired of paying for TV sports channels they don’t watch will soon have a new option.

Cable channels owned by Discovery Communications, Viacom Inc., AMC Networks, A+E Networks and Scripps Networks Interactive will be part of a new streaming service expected to have a “soft launch” in coming weeks, people familiar with the situation say.

Subscriptions will cost less than $20 a month.
