Seconding Planet Money (http://www.npr.org/blogs/money/), in fact the whole Marketplace team is pretty stellar (http://www.marketplace.org/marketplace-podcasts)

TWIT is always pretty fun as well (http://twit.tv/show/this-week-in-tech/)

Smithsonian puts out an interesting presentation every so often too (http://www.si.edu/podcasts/)

Granted these are all great podcasts, but they've been around and entertaining way before 2012.
