Example: The message: "Stand up for the arts! Keep Ovation on the Air."
In 2012, Time Warner Cable's plans to drop Ovation - a television channel dedicated to the arts and contemporary culture - inspired a social media campaign, live events, and attracted news coverage. Almost 90,000 people signed their online petition. Time Warner returned Ovation to its service in fall, 2013.
