Radius Inc is to sell off the business that made its name to Korean monitor manufacturer KDS, another victim of the falling sales of Apple computers. KDS America has agreed to pick up the business for just $6.2m. Radius will concentrate instead on the digital video software and color calibration business it’s been building up over the last few years. Mountain View, California-based Radius, best known for the Macintosh monitors that became widely used in the publishing and pre-press industries, was founded in 1986. It built up a successful business supplying monitors for high-end Macs, until it overreached itself in the mid 1990s by acquiring SuperMac Technologies Inc and entering the doomed Mac cloning business. But more recently it has concentrated its efforts on digital video software such as PhotoDV, a still captive offering for DV camcorders. KDS, part of the $1bn Dugo Business Group, acquired the monitor business of German company miro Computer Products AG last year, and will use the miro Displays unit to deliver Radius branded monitors through a single, worldwide organization. It says its combined monitor operations will now equal $100m in sales for the year.
