Real time within the media is a method in which events are portrayed at the same rate at which they occur in the plot. For example, if a film told in real time is two hours long, then the plot of that movie covers two hours of fictional time. If a daily real time comic strip runs for six years, then the characters will be six years older at the end of the strip than they were at the beginning. This technique can be enforced with varying levels of precision. In some stories, every minute of screen time is a minute of fictional time. In other stories, such as the daily comic strip For Better or For Worse, each day's strip does not necessarily correspond to a new day of fictional time, but each year of the strip does correspond to one year of fictional time. Real time fiction dates back to the climactic structure of classical Greek drama. Film, television and radio Often, use of split screens or picture-in-pictures are used to show events occurring at the same time, or the context in which various subplots are affecting each other. Examples include the television series 24 and films Timecode and Phone Booth. On-screen clocks are often used to remind the audience of the real time presentation.
