Sound Blaster is a family of sound cards and audio peripherals designed by Singaporean technology company Creative Technology (known in the US as Creative Labs). The first Sound Blaster card was introduced in 1989, and since then, the Sound Blaster brand has become synonymous with high-quality computer audio. Sound Blaster sound cards were the de facto standard for consumer audio on the IBM PC compatible system platform, until the widespread transition to Microsoft Windows 95, which standardized the programming interface at application level (eliminating the importance of backward compatibility with Sound Blaster), and the evolution in PC design led to onboard audio electronics, which commoditized PC audio functionality. By 1995, Sound Blaster cards had sold over 15 million units worldwide and accounted for seven out of ten sound card sales. The history of Creative sound cards started with the release of the Creative Music System ("C/MS") CT-1300 board in August 1987. It contained two Philips SAA1099 integrated circuits, which, together, provided 12 channels of square-wave "bee-in-a-box" stereo sound, four channels of which can be used for noise. These ICs were featured earlier in various popular electronics magazines around the world. For many years Creative tended to use off-the-shelf components and manufacturers' reference designs for their early products. The various integrated circuits had white or black paper stickers fully covering their top thus hiding their identity. On the C/MS board in particular, the Philips chips had white pieces of paper with a fantasy CMS-301 inscription on them: real Creative parts usually had consistent CT number references. Surprisingly, the board also contained a large 40-pin DIP integrated circuit, bearing a CT 1302A CTPL 8708 (Creative Technology Programmable Logic) serigraphed inscription and looking exactly like the DSP of the later Sound Blaster. This chip allows software to automatically detect the card by certain register reads and writes.
