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.

Afternoon roundup: Slate snaps up NPR’s Pesca; nonprofits join push to block KMBH sale

• NPR sports reporter Mike Pesca is leaving the network to host a daily current-events podcast for Slate, Business Insider reports. The show will begin this April. Pesca has co-hosted Slate’s sports podcast, “Hang Up And Listen,” since 2009. He tells BI he will have more license to share personal opinions as a podcast host, something he couldn’t do as an NPR reporter. Slate earns upwards of 10 percent of its total advertising revenue from podcasts and expects to grow that share in coming months, according to BI.
