Smithsonian via satellite

The Smithsonian’s controversial cable television programming will debut Wednesday, but right now only those with a specific satellite dish will be able to see it.

Subscribers to DirecTV, one of two main satellite TV carriers, will have access to the 75 hours of programming from the Smithsonian Channel, produced in cooperation with Showtime Networks, the network announced Monday.

Several groups objected to the contract because the Smithsonian signed over to Showtime semiexclusive rights. Showtime is the producer; the shows, which explore the history, natural world, cultural, and air and space subjects found at the Smithsonian, will not be seen on its network.

Since the deal was made public 20 months ago, Smithsonian officials have defended it as a way to make the museums accessible to more people and as a new source of needed money. The Smithsonian initially is getting $500,000 a year.
