Every week we round up media news you may have missed while you were busy exposing payday lenders.

• The Associated Press is planning to introduce sponsored content to its website and mobile apps next year:
  

  
  The move to sponsored content is part of a broader effort to open a new line of revenue at the AP, where just 2% of total revenue comes from advertising, including mobile banner ads and units across a handful of websites populated with AP content. Another 13% of comes from services the AP offers media outlets. And 85% comes from licensing content to subscribers such as TV stations, newspapers and websites, where the AP is not hopeful about expanding income.
  



• BuzzFeed is creating an investigative reporting unit to be led by Mark Schoofs, who won the 2000 Pulitzer for International Reporting while at the Village Voice:
  

  
  “We are very proud of the quality of our long form content, we have built a top flight news desk, we hired a foreign editor and correspondents around the world, and we are building an investigative journalism team,” [BuzzFeed founder Jonah Peretti] said. “And we’ve become profitable while making these investments.” The new investigative desk is the latest in a seemingly endless series of expansions for Buzzfeed, which brought Ben Smith over from Politico at the beginning of 2012 to add originally reported news content and aggregation to a site already well known for captivating Facebookers and Twitter users with listicles and pictures of cute animals.

• Should coding be required curriculum for j-school students? At a very basic level, yes, says Robert Hernandez, the same way colleges require all students to take general education courses such as science and math, regardless of what they are majoring in:
  

  
  You may have forgotten this, but once upon a time, you probably hated that you were required to take some of those general education courses — math, science, a language. But those same courses — or maybe it was philosophy, or psychology — changed the way you thought and viewed life. If you had a choice back then, though, many of you probably wouldn’t have taken those courses if they weren’t required .. I do agree that not all journalists need to learn and master coding in JavaScript, Python, or Ruby. But they should know that it is not magic and, to be successful in their modern careers, they need to be able to communicate and work alongside different experts, including programmers. They need to be, at a minimum, digitally literate.
