The following video is part of our "Motley Fool Conversations" series, in which Motley Fool senior technology analyst Eric Bleeker and chief technology officer Jeremy Phillips discuss emerging trends in technology.

In today's edition, Jeremy and Eric look at the struggles Pandora is having monetizing its exploding growth on mobile. Only about 1% of ad spend is on mobile despite 70% of its usage being on mobile devices. That's a huge gap, and it underlines the extreme difficulty of having an advertising model in mobile or Internet multimedia in general. Eric and Jeremy suggest that if investors want to try investing in the growth of media on the Web, they look to companies with a higher level of recurring revenue from a large subscriber base.
