LOS ANGELES — DirecTV subscribers have lost “SpongeBob SquarePants,” “The Daily Show” and “Mob Wives.”

Unable to reach a deal with Viacom, parent of several popular cable channels, including MTV, Nickelodeon, Comedy Central and VH1, DirecTV is no longer carrying the media giant’s networks. DirecTV has almost 20 million subscribers around the nation.

Both sides blamed each other for the channels coming off of the satellite broadcaster on Tuesday evening. Viacom said DirecTV dropped the channels without warning. DirecTV countered that its hand was forced by Viacom.
