So, what did Zenith do to make their CRT's fail quicker?

I think we all know that in the early 1990's, Zenith decided to make their CRT's last only about ~3 years before becoming too dim or failing outright. What I've wondered is exactly how they went about doing this? Did they use less emission materials in their color guns? Did they use under rated color guns (Like color guns meant for a 19 inch TV put into a 27 inch CRT)?

I've heard that weakening the vacuum in a CRT will make it fail quicker. Could this be what they did?
