One reason why it didn't go national, according to a project leader I worked under, was that the target market, housewives, didn't want to deal with their friends seeing them before they did up their hair and make-up in the morning. (this was the 60s, when homemakers could still be seen strolling through the grocery stores in house dresses and curlers. The real target market was the upscale women, or the upper 10%. For some reason, the business applications of the program seemed to be ignored. Still, by the time it was released in 1990, shortly after I joined the company, it wasn't a very good system. Part of that was the tech used in the phone, the other part was due to the infrastructure of the communications network. If you get a chance, there was a book by one of their former executives, called The Yellow Pages, that pointed out a lot of the company's less than sterling actions.
There are too many reasons put out that point to businesses not being trustworthy and holding the status quo. Innovations are slow in coming. I even stated though, that a "cure" for cancer would be difficult because there are so many cancers. But take the current look at medical marijuana. For decades, drug companies have fought it's legalization because they had other wonder drugs that cost a lot more. It's only in the last few decades that it's gained some headway as a method to treat glaucoma, epilepsy, Parkenson's, as well as counter the effects of chemo. One chemist that I corresponded with on another forum, that had worked for the drug companies said that they can make synthetic THC that was legal, so natural THC isn't needed. Huh? One of our club members had it prescribed to him because he was going through chemo, said outright the difference between the the synthetic THC and pot was like comparing Margarine to Butter. It ain't the same.
So, yes, the drug companies have not earned my trust.
