Late Wednesday, siouxcityjournal.com was the first to report on the expansion of Stream’s contract call center in Sergeant Bluff, “Stream addign 300 jobs.”

The suburban Boston-based company attributed the new hiring, which will raise total local employment to about 1,100, to added business growth by the clients the local call center supports. They include Sirius XM, Apple, Nike and Intuit.

Could the “cash for clunkers” auto incentive program be contributed to at least some of the Sergeant Bluff growth growth. The Wall Street reported Thursday that Sirius in the third quarter began adding satellite radio subscribers for the first time since December, “Sirius makes strides in third quarter.”

Sirius XM, which ran into financing difficulties that nearly sent it into bankruptcy early this year, before Liberty Media Corp. took a 40% stake, got a boost during the third quarter from cash-for-clunkers, the federal goverment program that paid consumers to trade in their gas-guzzlers for new, more fuel-efficient models.

The purchase of many new models comes with a subscription to Sirius XM. To activate the service, owners must call an 800 number. Customers service representatives at the Sergeant Bluff center handle many of those inbound calls, helping Sirius subscribers not only set up their service, but also answer questions about it afterwards.
