Pony Music Video

PMV, in the context of My Little Pony, stands for Pony Music Video. It is a type of fanvid made using focusing on the cartoon My Little Pony: Friendship is Magic (and at times, its spinoff My Little Pony: Equestria Girls, though videos using said spinoff can also be called more specific terms such as EQGMVs). They can be blended with other incarnations of the My Little Pony franchise, such as My Little Pony Tales, or with other fandoms entirely, such as Gravity Falls, just as long as Friendship is Magic is the main focus. They can sometimes involve, or be comprised entirely of, original animation based on the series.

Pony Music Videos are not to be confused with Picture Music Videos, although both are commonly abbreviated as "PMV".

Stylistic themes
Styles are extremely numerous and diverse. There are PMVs which consist entirely of original animation. There are PMVs which are raw edits. There are PMVs which heavily use visual effects. There are abstract PMVs, which are nearly always made in After Effects. There are comedic PMVs, and conversely, just as many dramatic ones.

Community
The PMV community, much like the rest of My Little Pony fandom, is highly disjointed and chaotic.

The popular fansite Equestria Daily has a PMV section.

Demographics
Every type of My Little Pony: Friendship is Magic fan is present, and both views and creates these; there are many such types, and they rarely interact with one another. For the first several years, the most prominent category of fan was the brony - a controversial faction of My Little Pony fandom which emerged from 4chan's comics and cartoons board alongside the debut of this series with little awareness of prior fandom history, and contains a disproportionate number of adult men. The other factions - older collectors of merchandise from all eras of the franchise, the children at whom the series is ostensibly aimed, and those with no ties to any group - are also represented. Over time, as the show's many seasons wore on, bronies began to lose interest, and therefore prominence; this led the other fans to become more prominent, with younger fans in particular gaining more and more of a presence in the video editing scene.

History
Pony Music Videos have been made by fans since the series first aired in November 2010. The first to arrive on the scene were early bronies; others quickly followed.
