Ninth House Inc. continues to distinguish itself with top-notch production values and extensive use of audio and video. In addition, its use of the CD-ROM to deliver high-band-width media has let Ninth House Inc. courseware move beyond the current text, graphics, and low-resolution small-box video used by many online courses. Although high-end graphics can enhance a program, it's still the underlying instruction that's most important, and the Ninth House approach is effective for illustrating key concepts. The extensive use of audio and video clips means less content is covered in depth. Not as much information can be conveyed by audio clips as by text. Much of the instruction is delivered through video clips, and there's a story about kids and a lemonade stand to illustrate the main points.
