Why do you call vinyl records records?

Vinyl records are called "records" because they were the first widely available method of recording and playing back sound. The term "record" was originally used to refer to the grooves that were cut into the surface of a wax cylinder or disc, which could then be played back by rotating the cylinder or disc on a phonograph. As vinyl records became more popular, they replaced wax cylinders as the primary means of recording and playing back sound, and the term "record" came to be used to refer to vinyl records specifically. Today, the term "record" can also be used more generally to refer to any type of recorded medium, such as CDs, DVDs, or digital audio files.
