My grandparents have phonograph records, do you know anything about that?
a phonohraph record is an analog sound storae with medium in the form of a flat disc with an indscribed modulated spiral groove. ever had one?
No I don't think I have, when were these used?
it was the primary medium for music reproduction until late in the 20th century. it had been around for nearly one hundred years i believe
Wow, do they know who invented them?
im not sure but the sonographic record co existed with the phonograph cylinder from the late 188s and superseded it at around 1912. it was once considered advanced technology!
That's fascinating, now we have crazy stuff like mp3 and mp4 technology.
yup. records retained the largest market shar even when other ormats of music were mass marketed like the compac cassette! people really loved them
