A busy week of media news on a variety of fronts this week; we’ll break it all down on Reliable Sources with this week’s guest host, David Folkenflik of NPR.

The much anticipated trial of former News International chief executive Rebekkah Brooks and former News of the World editor Andy Coulson began in London this week. Brooks, Coulson and six other defendants face a range of charges related to alleged phone hacking by journalists at the News of the World. We’ll discuss this significant media trial with The Daily Beast’s Peter Jukes, who has been tweeting from inside the courtroom, and Emily Bell, former editor-in-chief of Guardian Unlimited. We’ll get context from CNN Senior Legal Analyst Jeffrey Toobin and attorney Lin Wood, who will discuss the legal differences between the US and UK when it comes to covering court cases.

Last Sunday, New York Times writer Bill Keller published a column based on a series of online exchanges he had with former Guardian reporter Glenn Greenwald. The two journalistic heavyweights discussed the state of modern journalism and their differing views on journalistic objectivity.  Both men will join us for two separate interviews to expand on their views.

Finally, this week saw the launch of Fusion, a new cable television channel formed jointly by ABC and Univision. Fusion aims  to target the rapidly growing “millennial” demographic, in particular English-speaking Hispanics. We’ll discuss Fusion’s goals and the challenges it will face with former OWN chief executive Christina Norman and Mark Hugo Lopez, Director of Hispanic Research at the Pew Research Center.

Tune in this Sunday, 11am ET.
