Prentice Hall has been a constant client of ours for the last 5 or 6 years. For them we produced their highly successful "CHEMedia" laser discs. This was followed by several teacher training tapes for use by Prentice Hall's sales division. More recently we produced another successful series to accompany their new Biology text. The series of laser discs - "BIOvue" consists of 5 to 10 minute videos shot all over the country featuring biology, and biologists, in action. The "BIOvue" series spawned the "BIOvue" CD-ROM which we developed and produced entirely in-house.
