Michael Urlocker, who writes the OnDisruption blog, has a column in today's National Post looking at whether satellite-radio can survive the growing popularity of the iPod in the mobile music battle. One fact that jumps out is that 70% of 2007's U.S. car models will have built-in iPod connectors, which will give the 67 million iPod owners another way to enjoy their devices. Urlocker, a former telecom analyst, suggests XM and Sirius must implement some "tough measures" to compete such as pursuing lower growth targets so they can become profitable, and "looking for marginalized customers who don't want or can't afford iPods". When it comes to the challenges facing satellite-radio, Mike and I are perfectly aligned.
