The intention is like bias, but often more calculated. When a news outlet is biased they might not know better, and they might just assume when a story matches up with their narrative, it is true because of confirmation bias. But, news organizations can also have intent; they can purposefully print a story in an attempt to achieve a goal. Often the goal is to rationalize the actions of their political party's candidates or further their political or economic interests.
Historically, a great example of this is "yellow journalism" in the early 20th century. "Yellow journalism" generally refers to newspapers that published sensational stories, skewed facts, and outright lies to influence opinion and sell papers.
