Sound Businesses: Profiles of companies and business models we are keeping an eye on.

Tom Sosnoff, Founder and Co-CEO of the online financial network tastytrade, says he holds out little hope for those media companies still trying to survive with a revenue stream based on advertising. Tastytrade, founded in 2011 with Sosnoff hosting data-driven conversations on options, has since developed a trading platform, tastyworks, and educational product line that draws over 110,000 people to its audio and video feeds daily. Sosnoff spoke with Karma Network’s Contributing Editor Michael Moran.
