What we know as DVD was invented and produced in 1995 by Panasonic, Sony, Toshiba, and Philips. DVD's offered a higher storage capacity than Compact Disc (CD's) while having the same dimensions.

Prerecorded DVD's are mass produced using molding machines that physically stamp data onto the DVD. Such disc are known as DVD-ROM. On these data can only be read and not written or erased. Finally blank recording CD's and DVD's were produced (CD-R, CD-RW, DVD-R & DVD-RW). There are a few types, writable and rewritable (RW) which can be written to erased and written to again multiple times.

Before DVD, Video Cd (VCD) was on the market in 1993. In that same year, two new optical disc storage formats were being developed. One was Multimedia Compact Disc (MMCD) backed by Philips and Sony and the other was the Super Density Disc (SD), supported by Toshiba, Time Warner, Matsushita, Electric, Hitachi, Mitsubishi Electric, Pioneer Thomson, and JVC.

Now with the invention and distribution of BluRay and even Bluray R, DVD's are all but obsolete.

I could continue through the history of other means of media storage, but we'd be here for a lot longer. I do believe that covers your question and then some.
