Compact Disc-Interactive, known more commonly as CD-i, is a multimedia format for optical discs developed by Philips and first used in devices in 1990. It was designed to combine CD audio and CD-ROM technologies to allow extremely versatile content on a compact disc including music, video, pictures, text, karaoke, and interactive software like video games.
Philips produced their own CD-i home consoles and also licensed the technology to over a dozen companies. The format was ready by 1988, started seeing public applications by 1990, but home players reach the market until 1991. The Although the format was designed with entertainment, educational, and training applications in mind, CD-i never took off in any of those areas, and CD-i really only became known for its video games. Even then, it didn't do very well with only around 200 titles. By 1994, the format was struggling and Philips tried to rekindle interest by opening the format and no longer requiring licensing, but it didn't help, and, by 1998, Philips discontinued the format.
During the 1990s, I only knew of one person who owned a CD-i player. A neighbor of mine with rich parents had bought him and his brother one (probably a CDI 910).
There were many different CD-i capable consoles made by companies like Philips, Magnavox, GoldStar, LG Electronics, Sony, and several others. Some companies released models only in specific nations. Probably the most popular console, at least in the USA, was the CDI 910, which is a special version of the CDI 205 released only in America.
