How current is current? When is an event considered history?

If you were to look at a current event, how current is current? When does it move from current in to the realm of history?

Let's define the idea of current: current means occurring in or belonging to the present time.
History is defined as a description of past events.

These two seemingly different terms "current" and "history" really are not as far apart as many of us would like to think. These two terms run parallel to each other. Yesterday's current event is now today's history.

For example, an article written about a event (we could take any event- For example, the recent awarding of the Noble Peace Prize to President of the United States, Obama) can now be seen as historical or history because it happened last week. Its no longer current, although it can be seen as recent.
