The CD celebrates its 30th birthday, looks forward to retro kitsch retirement

Like so many other technologies, it's tough to pin down an exact birthday for the compact disc. If we're tracing things back to the world of LaserDisc as a potential commercial product, we're talking years or decades earlier. As far as laboratory testing is concerned for the tech as we've come to know, love and subsequently abandon, the we're going back to the mid-70s in our journey. For the sake of simplicity, let's go with the first commercial record to be released on the format. That would be 52nd Street by one William Martin Joel, a release that came a few years after the album's issuing on vinyl, to coincide with the Sony's CDP-101, which let audiophiles do more than just stare in wonder at the shiny plastic disc they just bought.
