What is it called (Specific name) when the president interrupts every channel on Television, and...speech.?

Barrack Obama recently..(15 mins ago) had a speech. My mom, 'the walking thesaurus.' made an attempt to call the title of the interruption...but couldn't think of the word. It's bugging the spit out of both of us,so if you know, please speak up. You'll be saving two girls from insanity. Thank you! ^^
