From a report on CNET: On a lark, Joel Wilson started developing skills for Alexa, Amazon's voice assistant, this past January. After a few weeks of coding, he launched two skills -- Amazon's term for voice-controlled apps -- called Question of the Day and Three Questions. Both quiz people on science, literature and pop culture trivia. In May, he got an email from Amazon telling him to expect a check in the mail as part of a new program that pays cash to makers of popular skills. That first month, Amazon sent him $2,000. It got better from there. He's received checks for $9,000 over each of the past three months, he said. Wilson unexpectedly joined a new Alexa economy, a small but fast-growing network of independent developers, marketing companies and Alexa tools makers. Two years ago, there wasn't nearly as much to do on Alexa and the market for making Alexa skills was worth a mere $500,000. Now, with more than 25,000 skills available, the market is expected to hit $50 million in 2018, according to analytics firm VoiceLabs.
