Aereo: Aereo has expanded coverage of its television service to include 19 million more users in the New York Metropolitan area, the company announced Monday.

The service, which captures broadcast airwaves and converts them to allows users to watch television on their Internet-connected devices, had previously only been available to area viewers in the five boroughs of New York.

Aereo announced in January that it would expand into 22 additional markets in 2013.

Mozilla and third-party cookies: Mozilla said Friday that it is changing its restrictions regarding third-party cookies in a move that it says will more closely mirror “user privacy preferences.”

The changes mean that Mozilla’s Firefox browser will block third-party cookies by default, according to a post from Stanford grad student and the policy’s author, Jonathan Mayer. Under the policy, only cookies from Web sites users visit directly can use first- or third-party cookies, meaning — for example — that ad networks such as Doubleclick could only track users who go directly to its Web site.

In a message to his Twitter followers, Interactive Advertising Bureau general counsel Mike Zaneis called the setting and the decision to turn it on by default a “nuclear first strike” against the online advertising industry.

GM, AT&T bringing 4G to cars: General Motors and AT&T announced Monday at the Mobile World Congress that they will work together to put 4G WiFi connectivity into cars starting in 2014.

The partnership, AT&T said, will allow the carrier to put safety, security, diagnostic and infotainment services in GM cars and trucks, as well as offer consumer features such as the ability to stream video from the back seat.

Verizon had previously held the contract to provide connectivity for GM’s OnStar service.

Barnes and Noble may move away from Nook: Barnes & Noble may move away from its Nook e-reader hardware, according to a Securities and Exchange Commission filing that outlines a bid for the company’s non-Nook assets from its founder, Leonard Riggio.

The New York Times reported that Barnes & Noble seems to be more interested in creating partnerships to license its content rather than building its own devices. The Nook has been a decent — but not runaway — success and has always played second fiddle in the e-reader market to Amazon’s Kindle devices. Barnes & Noble has been expanding its Nook line, introducing larger tablets last year with high-quality screens.

LG buys HP’s WebOS, for TVs: LG announced Monday that it has bought Hewlett-Packard’s WebOS system, a platform that had been widely praised but fell by the wayside when HP announced it would not longer make hardware for the system. A report from CNET was the first to detail the deal. LG has reportedly said that it will use the WebOS system in its televisions.

WebOS had been available as an open-source project to give outside developers a chance to look under the system’s hood and make their own modifications; LG told ZDNet that WebOS will remain open source.
