The reason for this is strictly ALL ABOUT MONEY! Technically, since Sirius and XM as separate companies supposedly no longer exist, we should be able to get the same content on all radios. But you will probably never see MLB on Sirius radios. Why? Not because Sirius XM can't do it, but because the want you to have to spend more of your money and buy a Mirge to get all the programming. And the fact that XM radios can't air NCAA tourney games because "they have an exclusive deal with Sirius is ridiculous! XM IS SIRIUS NOW, AND SIRIUS IS XM- THEY ARE BOTH THE SAME. SIRIUS BY ITSELF NO LONGER EXISTS. How can you have an exclusive deal with a company that no longer exists?
