PBS has produced this video as part of its series Off Book. From the PBS site comes this description:
Type is everywhere. Every print publication, website, movie, advertisement and public message involves the creation or selection of a fitting typeface. Online, a rich and artistic typographical culture exists, where typefaces are created and graphic design seeps in to every image.In episode 2 of Off Book, typeface designers Jonathan Hoefler and Tobias Frere-Jones outline the importance of selecting the right font to convey a particular feeling. Graphic designer Paula Scher talks about building identity in messaging, while Eddie Opara uses texture to create reaction. Infographic designers Julia Vakser and Deroy Peraza map complicated data sets into digestible imagery, mixing color, graphics and type.
