Research in Motion, now BlackBerry, debuts system:

Research in Motion announced that it is rebranding itself, taking the name of its flagship technology and dropping the name its held for more than 25 years. Now BlackBerry, the company debuted its new system, showing off deep social integration, separation between work and personal data and updated designs that look more like popular handsets from Apple and Samsung.

BlackBerry released two models running the new system, one with a physical keyboard and one without, that showcase a software that allows users to move quickly between applications, play media files and post to social networks.

Many consider this launch to be BlackBerry’s last chance to truly compete in the smartphone space in the face of the iPhone and smartphones running Google’s Android system. A shrinking but loyal audience of users have held on to their BlackBerrys as the company has struggled to innovate. To maintain and grow its subscriber base, the company will have to push hard to get its phones back into the hands of corporate and government customers.

Judge denies increase to damages in Apple-Samsung case: Judge Lucy Koh ruled Tuesday to uphold a jury’s ruling that directs Samsung to pay Apple more than $1 billion in damages.

The judge did not, as Apple had requested, triple damages in the case by finding Samsung had “willfully” infringed on patents. She has yet to rule on Samsung requests to reduce the charges, on the basis that claims of certain Apple patents were not valid.

Apple and Samsung are locked in a tight race for the smartphone market, with recent data from International Data Corp. showing Samsung has a 29 percent share of the smartphone market to Apple’s 21.8 percent.

Facebook earnings: Facebook is set to report earnings Wednesday, coming off a 50 percent increase in its stock price as it works to build its strength in the mobile advertising space.

Facebook has the most popular app in the United States — alone, it accounts for 23 percent of all U.S. app use. But that distinction is a mixed blessing.

Mobile advertising does not make as much money as ads that appear on laptops and desktops, and it’s much harder to catch a user’s eye on a smaller screen. Just 14 percent of Facebook’s revenue came from mobile products last quarter. That number must jump, a lot, to meet analyst expectations in its fourth-quarter earnings report Wednesday.

YouTube considering paid subscriptions: YouTube is considering introducing paid subscriptions to its content, Advertising Age reported, which would mark a major shift in the Google-owned property’s approach to making money off the growing online video trend.

YouTube has made a serious investment in the past year to improve the quality of content on the site and making more original series and shows. The site has declined in the past to say how much its content producers make from advertising-sharing agreements, saying only that hundreds of producers make at least six figures annually.
