Sirius Satellite Radio has launched a national print and retail advertising campaign today, which sets forth the "Sirius Guarantee."
The guarantee clearly states that no Sirius radios will become obsolete as a result of a merger with XM.
Customers who sign up now for Sirius will have their subscription rate honored by the merged company.
Following the merger, Sirius expects to offer "the best of both services" in a mix of programming. But they're assuring customers that 100% commercial-free music, as well as top on-air personalities like Howard Stern, Martha Stewart, Cosmo Radio, Playboy Radio and others will continue to be offered.
It's nice to see both XM and Sirius individually making these commitments to subscribers, though I doubt it will have much of an effect on those who are generally cynical of the deal.
Until we know what channels make the cut - something we won't know until the deal gets approved - there will always be the shadow of doubt looming. This will need to be a continual PR/Marketing effort throughout the year until the deal is finalized.

What a coincidence! XM made an almost identical guarantee THIS VERY DAY!
Wow I guess Sirius copied XM right? I wonder if Mel and Gary even had a discuss about it. Grow up.
Hoo Hoo, I invented promises Robin .... tell em Fred!
All pests, please go away!
does this now mean that bubba will promise to get a babysitter so he can face off with OnA in the octagon?
do you smell a merger a-cooking? i just got a brand new sportster 4 cheap off http://www.sirius.com/freeradio and i have no regrets. here in san diego, the signal's pretty good; not awesome, but pretty good. reading this, i'm just happy that everything is falling into place and that i don't have to worry about network/operator compatibility issues.
