Thanks very much for your comments, David. I included "MSO" and "HFC" in the list primarily for newcomers to the industry. You'd be surprised at how many people (including those who have been around the industry a while) don't know what "MSO" means or don't know its correct definition, and even more who misuse it. "HFC" is another abbreviation that surprisingly falls into that category. There were many other abbreviations and terms that I wanted to include in the blog, but I already exceeded somewhat my word count limit. :-) That said, I've been working on an in-depth abbreviation list the past few years, and it's up to 80+ pages and 3000+ entries. SCTE has already used some of that list in their on-line abbreviations reference.
