Sirius and XM are working on handheld portable receivers in their bids to dominate the satellite radio market. XM already is the dominant player with 2.5 million subscribers, MLB games, "Opie and Anthony" and Honda and GM as partners.
Sirius has gained 800,000 subscribers after signing Howard Stern on, and it hopes its deal with Ford and Chrysler and airing of NFL games will continue to attract more people. One thing it has to contend with is XM's MyFy portable satellite radio.
Sirius is expected to announce a similar portable radio soon. The two companies are also working on a device that works with both networks but it could take years to hit the market. Meanwhile, the competition continues.
