Well, if you listened to Rob Enderle of Enderle Group (www2.sdtimes.com/pdf/SDTimesBackIssues/sdtimes184.pdf) you might think that Rapid Application Development (RAD) is dead or dying. However, I think it's important to distinguish between two different things that are often lumped together and called RAD. One is the RAD development methodology and the other is 4GL tools that were often used in RAD development.

The RAD methology originated with folks such as James Martin of IBM and was proposed as an alternative to the Waterfall model. Its principal components included JAD (joint application design) meetings, the development of rapid prototypes, followed by iterative development until the working product was deemed complete enough. To facilitate RAD, there was an emphasis on the development of fourth-generation language (4GL) Integrated Development Environments (IDEs) that allowed for rapid development of the graphical user interface (GUI). PowerBuilder was originally one of those 4GL tools.
