The Internet and social media can provide immediate message dissemination and a wide variety of formats. A Web site can incorporate many different types of media and accessibility features, but the recipient must choose to access the site or have signed up for automated message feeds. Social media provides almost instantaneous messaging to those who have access.

Advantages:

• Internet—Updated quickly, can incorporate varied media (e.g., print, photos, graphics, audio, video, live streaming).
• Social media—Very flexible; messages can be short and quick.
• Individuals can opt into notification systems (Twitter, etc.)  that push messages to the recipient.

Limitations:

• Internet—Updates may only be at certain times.
• Social media—Limited control once the message goes out.

Requirements: Vary according to the medium and type of message.
