I have to agree with you Steve.
Bill might have seen this as an opportunity to throw in a few words of company promotion alongside his correction of the history, but equally people should remember the industry wouldn't be where it is today without BB or Pangolin. Many of the innovations we see today that make modern shows possible have come from Pangolin, such innovations as Projection Zones and Beam Attenuation Mapping to name just two, and some of those such as those relating to safety, BB chose not to patent for the good of the industry.
