The death of Queen Elizabeth II is a sad moment for the United Kingdom. The British Broadcasting Corporation has activated its protocol for handling the death of the monarch after standing at the ready for decades.

The plans called for all programming to be stopped and a display of the network's famous logo to be shown before a unified message was broadcast.

The news of her death broke first on social media with a post from the royal family. Within minutes, the account had more than half a million followers.

Two minutes later, the radio station's account appeared on social media.
