When Facebook Inc. wants to try something new, one of its first calls is to CNN., reports BloombergBusinessweek, which added that it was “a key partner when Facebook introduced its news-reading app, Paper, in 2014. When the social network shuttered Paper soon after, transmogrifying it into a series of fast-­loading News Feed stories called Instant Articles, CNN remained on board. And last year, when Facebook began focusing on hosting live video, CNN was one of the few parties to which it paid a nominal fee to produce clips of, say, election results being projected on the Empire State Building.

“But strain is showing in the relationship. Facebook’s latest pitch to publishers such as CNN is for them to provide a regular stream of TV-quality, edited, original videos that will give Mark Zuckerberg’s company a chance to compete with YouTube to siphon some of the $70 billion pouring into TV ads each year. In exchange, the publishers can share some of the revenue for ads that roll in the middle of the videos. Facebook will control all the ad sales.

“It’s getting tougher for CNN and others to view these arrangements as mutually beneficial.”
