After months of preparations, CBS News is widely expected to launch CBSN, a new always-on “feed” distributed via broadband, part of an effort by CBS Corp. to burnish the work of its venerable news unit without having to build out the old-school infrastructure, like a cable network, that would have been de rigeur in a different era.

The launch, a formal announcement of which is expected, was described by Jim Lanzone, president and chief executive of CBS Interactive, during a session at an industry conference in Dublin, Ireland. Digital-news site re/code previously reported the details.

Lanzone did not specify the name of the service, but executives have been mulling use of the name CBSN, and that name seems likely to stick. CBS News correspondents Jeff Glor and Elaine Quijano are expected to figure prominently in the new video-streaming effort, though a wide variety of correspondents from CBS News are likely to take part.

The new-tech service would give CBS more of a foothold in what has become a minute-by-minute churn of news and information being issued from breaking-news bots on Twitter as well as  the usual cable-news suspects, like Fox News, CNN or Al Jazeera America. Getting up to speed in a new era of broadband-distributed content is paramount for TV-news players, who are seeing their audiences defect to social media and mobile devices to get the latest developments in sports, weather, business and news of national and international import.

Indeed, Pew Research data shows that “between 2010 and 2012, the number of U.S. adults who said they watched cable news regularly fell 5 percentage points, from 39% to 34%. Meanwhile, the percentage of people who said they got news regularly from social networks rose 13 points to 20%, and those who got news regularly from a mobile device rose 6 points to 15%”

Already, CNN has launched a service it calls CNNGo that allows viewers to choose the video segments they want to stream. NBC  News is the owner of Breaking News, a service that sends headlines via digital feeds when it discovers reliable accounts of news.
