AT&T ( T) is looking to enter the e-book market as the company seeks ways to generate additional revenue, reports say. The market is dominated by Amazon.com's ( AMZN) Kindle reader, which uses Sprint's ( S) wireless network to provide near-instant access to a store with 100,000 books. Kindle has done a "phenomenal job" and AT&T wants to be part of that market, said Glenn Lurie, head of emerging devices at AT&T, reports Bloomberg. Meanwhile, Verizon Wireless said Wednesday that five companies have approached the company about wireless connections for e-readers, the Associated Press reports. Verizon Wireless is a joint venture of Verizon Communications ( VZ) and Vodafone ( VOD). "You're going to see a lot of e-readers out there," said Tony Lewis, who heads an initiative within Verizon Wireless to provide access to non-phone devices. "The interest level is tremendous." Lewis wouldn't say which manufacturers Verizon has been talking to, but hinted they are looking at entering parts of the e-book market that the Kindle doesn't focus on, like college textbooks. Amazon launched the second version of the Kindle a month ago. So far, the Kindle's main competitor has been Sony's ( SNE) Reader. AT&T's Ralph de la Vega, the company's head of consumer services, said since AT&T's network is more similar to ones used overseas it could support international e-book readers, AP reports. The Kindle can download books only in the U.S.
