At one time PV-Wave and IDL were the same product. IDL was developed by
Research Systems, Inc. At one point RSI entered into a contract with Precision
Visuals to market IDL under the name PV-Wave. Apparently part of this contract
gave Precision Visuals (now Visual Numerics) the right to buy out the source
code and go off on their own. So now IDL and PV-Wave are now separate and
competitive products with a common heritage. Each has been substantially
augmented since then. A lot of things, like the basic command syntax, are the
same for the two products (a lot of procedures can be used in both with little
or no modification), but a significant fraction, such as widget support, are
different because they were added or modified after the split.

This is all explained in gory detail in the FAQ which is posted once a month.

P.S. I tried to do a direct reply, but it didn't go through for some reason.
