Welcome to the 257th episode of the Inc. Uncensored podcast. I'm Inc.'s senior writer, Christine Lagorio-Chafkin.

Every year, Inc. sets about finding the industries that offer the greatest opportunity for entrepreneurs. We crunch the investment and revenue numbers and talk to experts, and eventually assemble a list of the eight best industries for starting a business in the next year. The process--and the selections--are always fascinating.

This year, the list includes space technology, sustainable consumer goods, and "healthy" junk foods. Senior editor Graham Winfrey and web producer Sophie Downes explain a few.

Virtually every office has a resident dog lover. Here at Inc. we have several, but staff reporter Cameron Albert-Deitch stands out as perhaps the most ardent. As part of the Best Industries package, he profiled Whistle, a company pioneering pet wearables.
