PV
From Wiki.theppn
PV stands for Promotional Video, more commonly known outside of Japan as a music video. Some J-Pop PVs have alternate versions such a "dance version" showing the artist dancing or a "close-up version" focusing on their face.
The term "PV" is also becoming increasingly popular and common in China rather than "MV" (music video). However, people in South Korean still prefer saying "MV".
