USA Today -- which veteran journalist Linda Ellerbee once described as the newspaper for people who find the evening news too complex -- is now available on Amazon's Kindle electronic reading device. The paper is said to be the top-selling newspaper in the U.S., with a total average daily circulation of 2.3 million and a daily readership of 5.4 million. A monthly subscription to USA Today costs $11.99. Kindle now offers subscriptions to a total of 29 papers. Most daily city papers cost less than USA Today; the New York Times and several European dailies are more expensive.
