The rumor mill says Apple and major car manufacturers are in talks to have podcasting be the new "car radio." While I won't speculate, there is no doubting that podcast listenership has grown over the years.

Thirty-three percent of Americans older than 12 have listened to at least one podcast, according to the Pew Research Center.

A strong sign that listeners are craving more podcasts came in the fall of 2014, when Serial became the quickest podcast ever to hit five million downloads.

With the increased listener base iTunes presents (along with Sticher and other third-party listening apps), podcasters are flocking to the platform and launching their own shows.

In fact, according to the Pew Research Center, at the end of 2014 there were 22,000 actively hosted podcasts.

This leads to the question: Of these 22,000, which ones should you skip and which ones should you quickly subscribe to?

Here's a list of the top 10 business podcasts of 2015.
