Pair with this animated 1937 guide to how radio works, this illustrated guide to making great radio starring Ira Glass, and these gorgeous vintage covers for Radio Times magazine.

For some fantastic post-wave modern radio, treat yourself to Design Matters by Debbie Millman, 99% Invisible by Roman Mars, and Radiolab by Jad Abumrad and Robert Krulwich.

Thanks, Alex
