FANTASY. The Fact is that Lyon's corp is PAID BY PBS to produce the
shows. In fact, in 1992 PBS shelled out 1.75 MILLION DOLLARS for 20
new episodes after viewers threw a tantrum at the decision to
cancel the show. That works out to 87 THOUSAND DOLLARS per show, or
nearly 3 Thousand per minute of air time!
