Kindle Connections Now Go to AT&T

In a business with true scale and scope economies, ownership of a global network can be a key advantage. Consider network support for the Amazon Kindle book readers, which now are sold internationally.

The U.S. version of the Kindle 2 has used the Sprint 3G network. But both international and U.S. versions will henceforth use the AT&T network globally. Existing U.S. Kindle owners will continue to use Sprint, but all new devices will be powered by the AT&T network.

Of course, there are other ebook readers. Barnes & Nobles sells the Nook, Sony sells the Daily Edition and Plastic Logic sells the Que. All of those readers use AT&T's network.

Verizon will provide service for the upcoming iRex e-reader.

The financial impact to Sprint might be a relatively minor issue. Sanford Bernstein analyst Craig Moffett estimates the Kindle will drive one million Kindle users a year to AT&T that Sprint would otherwise have gotten.

Moffett estimates that Sprint makes about $5 for each subscriber addition and $2 per every e-book downloaded onto Kindle over its networks, according to Business Week writer Olga Kharif.

The real issue is whether other upcoming devices and services have enough of a global angle, and enough sales volume, that providers such as Sprint are unable to compete in those new lines of business as well.
