The first Loebner Prize competition in 1991 led to a renewed discussion of the viability of the Turing Test and the value of pursuing it, in both the popular press  and academia.  The first contest was won by a mindless program with no identifiable intelligence that managed to fool naïve interrogators into making the wrong identification. This highlighted several of the shortcomings of the Turing Test (discussed below ): The winner won, at least in part, because it was able to "imitate human typing errors";  the unsophisticated interrogators were easily fooled;  and some researchers in AI have been led to feel that the test is merely a distraction from more fruitful research. 
As the debate blazes, deep-pocketed big tobacco investors are buying up e-cig companies, injecting millions of dollars into the market and banking on a bright future for the devices. More than 100 e-cigarette companies are now jockeying for the business of smokers and nonsmokers alike. The success of all these enterprises hinges on the claim that e-cigarettes are healthier than traditional cigarettes. Companies like to paint a black-and-white picture of a new era of safe smoking. “Cigarettes, you've met your match,” NJOY proudly proclaims in its Super Bowl ads. Whether e-cigs are genuinely safe is far hazier.
