Micromedia refers to short-form, real-time sharing of personal content like text, photos, videos and audio, typically through microblogging services. These services allow for conversational sharing of content in 140 characters or less, 30 second videos, photos or 10 second audio clips. While the content is short, micromedia is about engaging in conversation, not shouting or spamming, and represents a new marketing formula focused on personal, real-time communication.
