Given the above definitions, a show or series can be categorized with a genre construction derived from the above general definitions, as in the following examples:

• "Damon Runyon Theater" A drama, as well as a collection of pieces (anthology) from the same source or author (e.g., Damon Runyon), or adapted from same. Hence we can categorize it as a Dramatic Anthology.
  
• "The Lone Ranger" A western, as well as a serial, appealing to and targetted toward a primarily juvenile audience. Hence we can categorize it as a Juvenile Western Serial.
  
• "The Great Gildersleeve". A situational comedy, but not necessarily a serial. Hence we can categorize it as a Situation Comedy

  "The Green Hornet" A Juvenile Crime Serial
