Facebook is adding a feature to sell news subscriptions on its mobile app. The feature was requested by publishers and is due out by the end of the year. The move is meant to "mollify" large media organizations including the New York Times, which publish stories on Facebook's Instant Articles platform that are largely read on the site rather than on the sites for which they were produced. — POYNTER

Facebook will reportedly launch its original, scripted TV shows late this summer. The social media site had production budgets of up to $3 million per episode, and will release the shows one at a time, rather than dropping a whole season at once the way its competitors Amazon and Netflix do. Facebook has already lined up a relationship drama "Strangers" and a game show "Last Late Standing." After multiple delays, the company is aiming for a July announcement and a possible August release. — CNBC

Facebook added a feature to celebrate the 20th anniversary of the fictional Harry Potter character. The feature allows users to cast "interactive spells" using their status updates. When users type in any of the books' four houses (Gryffindor, Slytherin, Ravenclaw, and Hufflepuff) the words change color and become animated. Clicking on any of the houses' names or the words "Harry Potter" causes an animated magic wand to appear. The feature is not universal, and may be subject to the user's browser or the country in which they're located. The feature will be available through July 3. — DAILY MAIL
