The EAS can only be used to relay audio messages that preempt all programming; as the intent of an Emergency Action Notification is to serve as a "last-ditch effort to get a message out if the [p]resident cannot get to the media", it can easily be made redundant by the immediate and constant coverage that major weather events and other newsworthy situations—such as, most prominently, the September 11 attacks in 2001—receive from television broadcasters and news channels. Following the attacks, then-FCC chairman Michael K. Powell cited "the ubiquitous media environment" as justification for not using the EAS in their immediate aftermath. Glenn Collins of "The New York Times" acknowledged these limitations, noting that "no president has ever used the current [EAS] system or its technical predecessors in the last 50 years, despite the Soviet missile crisis, a presidential assassination, the Oklahoma City bombing, major earthquakes and three recent high-alert terrorist warnings", and that using it would have actually hindered the availability of live coverage from media outlets.
