Fictional videos are based on made-up stories and aim to maintain a sense of realism through believable narratives, characters, lighting, camerawork and dialogue delivery by actors. The target audience for fictional movies like Indiana Jones is typically younger audiences but can also attract older fans of any source material. These movies entertain audiences by transporting them to an imaginary world. Factual videos like the BBC documentary "The Life of Mammals" present non-fiction information about real events, people and nature to primarily educate middle-aged viewers. Promotional videos advertise products through sponsored messages using techniques like relatable spokespeople, catchy jingles and settings tied to the item to interest target customer demographics.
