What is what does pv mean in anime?

PV in anime stands for "Promotional Video". It is a short clip or trailer that is released prior to the official premiere of an anime series or movie. The purpose of the PV is to generate interest in the upcoming release and provide viewers with a sneak peek of what they can expect from the show or movie. PVs can be found on various platforms such as YouTube, social media, official websites, and events such as anime conventions. They often include scenes or footage that are exclusive to the PV and not shown in the actual anime release itself.
