Morning roundup: SCOTUS sets Aereo date, Burns gets GIF’d

• The U.S. Supreme Court has set a date for ABC TV v. Aereo, a challenge to the startup service that allows subscribers to watch TV programs over the Internet via miniature antennae. Oral arguments are scheduled for April 21. Though ABC brought the lawsuit, filed in New York and Boston, PBS and New York’s WNET are also among the parties claiming Aereo violates copyright law. • Ken Burns participated in his first Reddit Ask Me Anything session Tuesday as part of the promotion for his new app. He laid out the planned release schedule for his next decade of films: The Roosevelts in September, A History of Cancer: The Emperor of All Maladies and Jackie Robinson  in 2015, Vietnam in 2016, Country Music in 2018 and Ernest Hemingway in 2019.
