Viacom networks MTV and Nickelodeon went off air for 17 minutes Wednesday to support students and others participating in National Walkout Day.

From 10 a.m. to 10:17 p.m., those networks -- as well as Viacom-owned BET and Comedy Central, went off the air. The 17 minutes honor the 17 victims killed in the Marjory Stoneman Douglas High School shooting one month ago on Feb. 14, when a 19-year-old former student opened fire.

Students across the country will take over MTV's social media accounts during the walkout."
