"I tell stories. Not all of them have happy endings. Not everyone makes it home," writes former "The Walking Dead" showrunner Glen Mazzara in a piece on "The Heartbreaking Necessity Of Killing Good Characters" -- a topic newly relevant in the wake of the "Breaking Bad" series finale in which protagonist Walter White died. Mazzara details what it's like when a character's death is revealed, both to the actor who plays him and in the writers' room: "Many actors immediately try to persuade you to change your mind. If the material's as good as it can be, you …

The move to digital journalism is not just "'about putting up your story on the web,' Guardian deputy editor Katharine Viner noted in an excellent speech on Wednesday," writes Matthew Ingram. "It's about a fundamental redrawing of journalists’ relationship with our audience, how we think about our readers, our perception of our role in society, our status. We are no longer the all-seeing all-knowing journalists, delivering words from on high for readers to take in, passively.”

Time Warner Cable and Univision signed a carriage deal for "several of Univision's new networks including the highly anticipated El Rey Network," writes Meg James. The partnership's financial terms were not disclosed, but "the pact came well in advance of the expiration of the companies' current arrangement and was not contentious," as other recent dealings between Time Warner and content companies (think of the recent CBS blackout) have been.

Goodby, Silverstein & Partners is handling the branding and ad campaign for investigative journalism nonprofit Center for Investigative Journalism pro bono.

Broadcast networks plan to file a petition asking the U.S. Supreme Court "to review lower court rulings that have allowed Aereo to continue offering unauthorized streams of digital signals in New York, according to sources familiar with the case," writes Ted Johnson. "The Supreme Court is prone to step in when circuit courts issue conflicting opinions, and there is a question as to whether the justices will take the case, or whether they will wait for the legal proceedings to play out further."

Twitter as TV channel?  In its first step in that direction, the social media network partnered with Comcast to allow NBC programs -- including "The Voice" and "Sunday Night Football" -- "available on Twitter directly from tweets," writes Scott Martin. "TV subscribers will need to log in to their pay-TV accounts."

Hearst Ventures is investing in an expansion of Swirl Networks' mobile app that helps shoppers at fashion stores.

Crew," writes Kyle Alspach.

Dennis Publishing's The Week magazine just hired Tim Koorbusch as its third publisher in as many years. He "has replaced Michael Wolfe, who joined the company at the beginning of 2012. Wolfe had replaced Jessica Sibley, who had put in 18 months on the job," writes Peter Kafka.

Renewal of Katie Couric's ABC daytime talk show, up for a third season probably this month, "seems a long shot," writes Alex Ben Block in an article whose analysis of  the problem includes some nasty behind-the-scenes comments, mostly from "former" employees."[Couric] has a complete and utter disdain for the audience she needs to appeal to," says one such employee. "In her mind, the Today show was [the model] -- professional women getting ready for work. Anyone home after 9 o'clock are people she has no interest in appealing to. But she also loved the $20 million paycheck."

Joanna Coles, editor in chief of the U.S. edition of Cosmopolitan, has increased the pub's circulation slightly in the year or so that she's held that post, but "her influence is nowhere more evident than in the magazine’s newfound interest in Washington and the political and policy matters that most directly affect women," writes Laura Sessions Step.
