By the time the late 1980s rolled in, a revolution of sorts happened in the audio recording industry that swept across the globe and forever changed the way we look at data storage and retrieval. Of course, we are talking about the introduction of the compact disc (CD). Considering its primary application, the CD offered superior sound quality when compared with the output from cassette tapes and LPs.

Thus, the conception of the CD ushered in an age where a universal standard for rewritable, recordable, and recorded media gave audiophiles and cinephiles alike the best quality and features for video and audio recording, which can all be theirs at a very low cost. In addition to this astounding leap in quality of audio and video recordings available to consumers, the initial 650-MB storage capacity of the CD woke up an insatiable thirst for more storage capabilities.

The demand for more storage space was met by the development of DVDs. If the CD could accommodate 650 MB of data, the DVD can take in up to ten times more than that. The evolution of the CD to DVD format paved the way for the development of high-quality audio and video recording, as well as the development of extremely demanding data applications. The physical aspect of the DVD, however, did not differ from the CD. And this pleased the consumers, considering that the similar form allowed for the seamless migration to the next data storage and retrieval format. Furthermore, the same form factor offered backward compatibility, i.e., CDs can still be played in DVD players.

At the turn of the millennium, the thirst for more data storage was stronger. The clamor for more storage space pushed innovators to develop the next-generation of data retrieval and storage media. The innovators are aware that the success of the next-generation media relies on its capability to accommodate backward compatibility and larger storage. Furthermore, its form should be in keeping with its predecessors.

Thus, Blu-ray Disc technology was born. With storage capacities of up to 50 GB (and more in future incarnations) per disc, it cannot be denied that it has truly surpassed its two predecessors. With the introduction of the Blu-ray Disc, high-definition video recording became possible. We now witness breathtaking imagery on our screens and crisp, clear audio courtesy of this technological innovation. Furthermore, interactive features integrated into videos allow for a more personalized viewing experience.

But does it stop there? At present, the innovators and inventors are still hard at work. Perhaps one day soon we will have in our hands another form of data storage. For certain, it will have higher storage capacities and will forever change our definition of quality entertainment.
