In this chapter, the author was hired to write a series of half-hour documentary-style scripts for a local college television station. The programs were part of a series of television courses on various sciences, which in his case was biology. Structure and transitions are critical in corporate media programs because they can have a profound impact on the script you may be writing or working with. If the structure is logical and the transitions subtle but effective, the result will be a clear, comfortable journey of enlightenment from which the viewer or reader will walk away knowing exactly what the writer had hoped to communicate. On the other hand, if the script is poorly structured and the transitions were weak, or even absent, the viewer will end up getting some of the information, but often in a choppy or disjointed way.
