Oh sure, there's a merger going on so everyone's one big happy family right? Not exactly. Everyone still wants to see how Sirius' and XM's satellite radio subscribers are stacking up against each other.

So here's some charts and numbers using the latest subscriber information to break it all down for you.

Total Satellite Radio Subscribers:

Sirius Satellite Radio: 7,142,538
XM Satellite Radio: 8,250,000

The above chart shows the total cumulative subscribers starting from the fourth quarter of 2001 and how both Sirius and XM subscribers have grown comparative to each other.

Quarterly Net Subscribers

Sirius Satellite Radio: 561,493
XM Satellite Radio: 338,000

Here you can see how Sirius and XM have added NET subscribers on a quarterly basis, going back to 2005. For the seventh consecutive quarter, Sirius has beaten out XM in net satellite radio subscriber additions.

Quarterly Gross Subscribers:

Sirius Satellite Radio: 1,002,145
XM Satellite Radio: 942,000

This chart shows the quarterly GROSS subscriber additions between XM and Sirius. I find that gross subscribers are a very important metric to track, because it eliminates variables (like churn) and shows the true market penetration. For the third consecutive quarter, Sirius has outpaced XM in gross subscriber additions. This even beats out the "Stern Effect" from last year.
