Subscribers to US satellite television service DirecTV will soon have free access to more than 70 XM Satellite Radio channels.

The two companies have inked a deal to compete with rival Sirius Satellite Radio and the partnership formed last year with DishNetwork.

Washington DC headquartered DirectTV, controlled by media magnate Rupert Murdoch's News Corporation, has nearly 15 million subscribers, a large pool from which XM can extend its own five million customer base.

Says Patricia Kesling, the radio company's vp of marketing: "We know from experience that when people get to sample XM, they want to become XM subscribers."

The offering to TV customers, due to start mid-November, is mostly music but also includes children's programming, some sport and the adult oriented High Voltage channel.
