Verizon

The company that fought last year to reduce the number of U.S. carriers from four to three says more competition in the smartphone market is a good thing.

Customers weren't thrilled when unlimited iPhone data plans ended, but none complained too much. Verizon got more expensive, but transparently. AT&T went with manipulation and cloaked accusations of data hoggery to push customers to tiered plans, or toward Verizon.

Netflix faces tough competition for its cloud-based TV- and movie-content-streaming service: carriers who not only have deeper pockets to pay for content, but own the wires and customer Internet accounts, too. Can Netflix survive? Or is it this decade's Napster?

AT&T posted a fourth-quarter loss thanks to pension costs and a break-up fee for the doomed T-Mobile acquisition, but said smartphone sales hit a new record.

Shares of Apple hit a new all-time high of 427.75 on Monday after two analysts raised their target prices.

For the third year in a row, AT&T is the lowest-rated wireless carrier in Consumer Reports' annual subscriber survey. There's something to be said for consistency.

Got a smartphone? Then Carrier IQ's software may be logging everything you do on it. Better start praying it won't get hacked.

The No. 3 U.S. wireless carrier is betting the company's future on Apple's iPhone. It probably doesn't have many other choices.

A federal judge has set a Sept. 21 hearing in the U.S. Department of Justice antitrust lawsuit opposing AT&T's purchase of T-Mobile USA.

When you're the No. 3 wireless carrier in the U.S. market, with about 17 percent market share and facing the prospect of a merger (AT&T's proposed $39 billion purchase of No. 4 T-Mobile USA) that could leave you battling two giants (the second one being Verizon), you can't lose subscribers. But that's what Sprint did -- 101,000 of them in the second quarter.

Major U.S. Internet service providers have agreed to help content producers fight copyright theft.

Android remains the most popular smartphone operating system in the U.S., but its market-share among new purchasers has stalled, according to researcher Nielsen.
