Later, due to the great increase in the number of people uploading video files, "up Master" gradually refers to video uploaders. It is worth mentioning that "up Master" was originally a name for video uploaders by video viewers, and was later used by some video uploaders as a self-name. Not all videos uploaded by "up owners" are the first ones. People who reprint videos from other websites and upload deleted videos again can also be called "up owners". In addition, "up Master" is also called "Grandma Master", and "Grandma" is a transliteration of up.
"po owner" refers to the person who posts posts, videos, audio and pictures on the Internet. "po" is the abbreviation of English post, which means "publish" here.
There are many similarities between "po Master" and "up Master", and there are two main differences between them: First, "up Master" mainly uploads video files, while "po Master" publishes more contents, and video files are only a part of them; Second, "up Master" is more common in barrage video websites such as Station A and bilibili, with a narrow scope of use, while "po Master" is widely used, and it can be seen in blogs, Weibo, forums, post bars and video websites.
In addition, the pronunciation of "po" is similar to that of "Bo" in "Weibo", and the word "po Master" appears frequently in Weibo, so some people think that "po Master" refers to the publisher in Weibo, but in fact it narrows the reference scope of this word.
