Now that the numbers are in, we can compare and contrast over one of my favorite metrics - gross subscriber additions.

For the second quarter in a row, Sirius has outpaced XM in the number of quarterly gross subscriber adds. This is pretty significant because historically XM has held the lead in gross subscribers. And gross subscribers are our purest form of tracking marketplace penetration.

As you can see in the chart above, the gap isn't quite as wide in the first quarter of this year as it was with the fourth quarter of 2006, but it's still a decent gap (~120k this quarter).

Sirius also managed to outpace the same period last year. Think about that for a minute. Last year we were in midsts of the Stern Effect, and Sirius still managed to edge out their previous gross additions.

That shows the power of OEM subscribers, regardless of the debate over "car lot subs" or not. As the satellite radio industry continues to shift into a largely OEM driven market, there's a strong growth curve ahead. They just need to make sure they keep that churn in check.
