If you read enough media reports, you'll begin to believe that the Internet will kill AM, FM, and even satellite radio. Connectivity drums up promises of choice (bad for conventional radio) and cheapness (bad for satellite radio). But the question's not that simple.

The Internet creates opportunities, even as it renders some media platforms obsolete. Furthermore, it'll take more time than you might think to seamlessly tie content floating out in the cloud to a box inside your dashboard.  

Nine lives
"Will the Internet Kill Traditional Car Radio?" asks a headline in yesterday's New York Times.

"The Internet's tentacles seem to have no limit, reaching out and strangling CDs, bookstores, newspapers and magazines," begins automobile columnist John R. Quain. "Now it has its sights set on the car radio."

Quain's thesis -- and I hate to call it his thesis, since it's shared by many industry watchers -- states that the growing popularity of smartphones and mobile hotspots makes it easier to stream Internet radio stations or tap into Pandora Music and other music-discovery sites.

His one test-drive beef is with AT&T's (NYSE: T) spotty 3G coverage in New York City, but "buffering" won't be the end of this revolution. Speeds of 4G and beyond will come quickly. In fact, Sprint Nextel (NYSE: S) is already marketing the Sierra Wireless (Nasdaq: SWIR) Overdrive mobile hotspot as the first 4G device on the market.

In other words, unreliability won't save radio forever on this front. However, pure practicality could help keep terrestrial radio on the air.

The high price of freedom
Connectivity doesn't come cheap these days. Music developers aim first for Apple's (Nasdaq: AAPL) pricey iPhone before trickling down to other devices. A monthly iPhone plan through AT&T starts at $70, and that's for just 450 voice minutes and no text messages. The pricing schedule ramps up quickly, topping out with a $120 plan for unlimited minutes and texting. AT&T does offer attractive family plans for additional lines, but we're essentially talking about a device with a limited audience in terms of affordability.

So what about the Overdrive through Sprint? Mobile hotspots are game-changers, because they allow as many as five devices to connect to a single wireless hub. In other words, you don't even need a pricey smartphone. An iPod touch can run Pandora -- and cars continue to make it easier to connect iPods into their speaker systems. However, Sprint's Overdrive will set owners back $60 a month.

Will smartphone and mobile hotspot plans get cheaper in the future? Don't be so sure. High-end smartphones by Apple and Research In Motion (Nasdaq: RIMM) are reasonably priced because wireless carriers subsidize the handsets, to the tune of hundreds of dollars apiece. Even though the carriers make up that shortfall during the course of two-year contracts, they're still on the hook to fund smartphone users' ever-growing appetite for unlimited data. Just ask AT&T, as it digs deep to overcome complaints of spotty coverage. Mobile hotspots are also typically subsidized.

So in all honesty, it's hard to imagine more than half of the country paying $100 or so for smartphone plans, or $60 a month for mobile hotspots. The potential market is big enough to dent terrestrial radio, but it won't obliterate AM and FM altogether.

Satellite survival guide
Satellite radio may be more susceptible than terrestrial to the Internet threat. Sirius XM Radio (Nasdaq: SIRI) has 19 million subscribers; if someone has disposable income to pay $15 a month for premium radio, they may also have the means for a smartphone or a mobile hotspot.

The key here is that satellite radio is a cheap alternative compared to fancier connectivity plans. A sufficiently large chunk of the market can afford a satellite radio subscription, but not a smartphone. Another significant slice of smartphone owners won't think twice about paying another $15 for XM or Sirius.

In other words, fears of satellite radio's doom are overblown. Sirius XM can pay up for premium content that ad-supported radio -- terrestrial or Internet -- can't afford. There's enough market to go around for everybody.

The real threat of Internet radio
"For the first time, small local stations will be able to reach an entire driving nation, so some broadcasters may see their audiences swell as more listeners find them on Internet-connected car radios," Quain concludes.

Unfortunately, I don't agree there, either.

After all, when Quain kicked off his column by suggesting that the Internet had vanquished CDs, bookstores, newspapers, and magazines, he missed the mark. The Internet didn't trip up any of those industries -- it just leveled the playing field, making powerful players less so. Major labels now have to compete with unsigned garage bands on MySpace. Print media publishers have to compete with blogs, public-domain content, and sticky sites that lure in consumers.

If every small radio station can broadcast to the world, they'll have to compete not only with every other station on the planet, but also with music-discovery sites -- or any hobbyist with time enough to create and stream their own playlist. A handful of savvy small-market stations could truly expand their audience, but for the industry as a whole, connectivity's growing popularity will be a net negative.

Thankfully for terrestrial and satellite radio, that day is far, far away.
