I'm sure if you listen to podcasts, you've come across Radiolab. A bit of popular science, life stories, what's not to love? It's great bit of fun and information rolled together.
If you like to know fun tidbits of info to throw into the mix, have a listen to Helen Zaltzman. She explains the history of words. I like her voice and she seems like a charming linguist!
I was a big fan of Gilmore Girls while growing up. I watched all the episodes when they aired and had the DVD box sets, so ended up watching them more than once. Kevin and Demi have grown on me and I enjoy listening to their analysis of one of my favourite shows from my teenage years. They do one episode at a time and are currently in Season 5 of 7. I'm looking forward to listening to their take on season 7 and their next show about Bunheads!
Murder, She Podcast
I love Angela Lansbury! I never watched Murder, She Wrote when it aired but recently started watching it after growing tired of all the dark TV (Game of Thrones, House of Cards, Homeland, etc.). It's a bit of cosiness. Jolene shares my love for Angela and she provides background on all the extras (there are so many!).
