When I do work for BET, HBO, CW Networks and INDEMAND it's called "PROMO" work. Therefore, I would make a "TV Promos" because I'm showcasing my skills as a promo voice talent.
Jamster, Toyota, Pizza Hut, Money are COMMERCIALS because you're advertising a product for sell, and that is considered a "Commercials"
I also play the voice of Action Snacktion the superpretzel, that can fall under Commercial, Character, or Animation demos because of it's wackiness, comedic timing and plain the ole' fact that I'm selling pretzels.
The radio stations I image all fall under the RADIO IMAGING helm
When you're story telling, about a person place or thing, it's called "NARRATION"
