At a roundtable event this morning at The Paley Center for Media, Sirius (SIRI) CEO Mel Karmazin was asked that very question. Does he worry about Stern leaving for an outfit–like Pandora–looking to avail itself of the same “Stern Effect” that spiked Sirius’s subscriber rolls?

Karmazin acknowledged that while it’s a possibility, he’s dubious. “I think it’s great to be content today,” he said. “In this world of fragmentation, great content prevails. Howard Stern is great content. Howard would be sought after by anyone. He’s a great talent. Having said that, we would like him to stay with us and we are optimistic that he will continue to do so.”

It’s worth noting that Karmazin, while he does view Internet radio as a competitor, doesn’t seem too worried by it. “There are a lot of choices for audio content,” he remarked. “And obviously, the Internet is one of them. But the question is who’s going to the the largest player? And I think that’s our spot to lose. I believe we will be the most profitable of audio content choices.”

Further Notes From the Event

On Amazon’s Kindle:
I am addicted to my Kindle. I saw Jeff Bezos in Sun Valley recently [and] I told him I have personally bought a dozen to give as gifts.

On Comcast/NBC Universal:
I dont’ see anything anticompetitive about what Comcast is doing–the review should take a few weeks. Either you accept the fact that there’s a lot of competition out there, or you don’t….But I do think this thing is going to drag out like it did for us. So far there are only two congressional hearings on Comcast/NBC. We had four–there were fewer for the Exxon Valdez.

On In-Car Internet and the Apple iPod:
I think the Internet will absolutely be in the car and we think it will be a good competitor. You know we’ve been competing with iPods for a long time. And we look at how sat radio performs in the vehicles where people have the ability to put an iPod jack in and we don’t see much of a difference. We believe them to be complementary.

“Speculation is rife that Apple will end its exclusive U.S. iPhone service deal with AT&T when the current contract expires in June 2010 and begin to offer phones that work with the Verizon network,” iSuppli analyst Francis Sideco said in a research note today. “However, iSuppli doesn’t believe this will be the case. The main reason Apple is likely to stick with AT&T beyond 2010 is the relatively wide usage and growth expected for the HSPA air standard used by the carrier for 3G data.”

As Sideco explains, “Cumulative global subscribers of HSPA wireless services, consisting of High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA), are set to rise to 1.4 billion in 2012, up from 269.1 million in 2009. In contrast, cumulative subscribers for the EVDO standard used by Verizon will amount to 304.6 million in 2013, up from 145.2 million in 2009.”

A point worth noting, though it’s hard to imagine that Apple (AAPL) doesn’t harbor some resentment toward AT&T (T), which has undermined its carefully crafted iPhone experience. And if that’s the case, wouldn’t it make more sense for the company to extend its deal with AT&T, but not as an exclusive? That would allow Apple to hammer out a second deal with Verizon (VZ), which, according to some analysts, would more than double U.S. iPhone sales in the near term.

As Bernstein Research analyst Toni Sacconaghi noted this summer, “Verizon’s postpaid subscriber base is not only larger than AT&T’s, but more importantly, is untapped whereas we estimate more than 10 percent of AT&T’s postpaid users already have an iPhone.”
