This trend is looking at analytics of political instances of media saturation. I call it Critical Mass. Despite consistent media we only see exponential gains on key events (Voting Day,Debates). This means we need to have the media infrastructure/network in place before we need it.

Possible reasons for this is:

• Humans outsourcing knowledge to calendars, social sites and other mediums. We only know a vague amount of information and rely on our knowledge to access it as a substitute for remembering.
• In a 24/7 multimedia cycle humans compartmentalizing knowledge to avoid over load.
