It’s also the perfect book for students of advertising and marketing.   Through the use of 70 years of print advertising, Kodachrome: How Two Guys Named Leo Changed Photography shows how the J Walter Thompson advertising agency sold the public on how easy it was to take professional-looking color movies and still photographs to an increasingly sophisticated audience over the course of decades.   Kodachrome: How Two Guys Named Leo Changed Photography is also a book for students of pop culture. What other film has a Paul Simon hit song, a major motion picture, and a state park named after it? This book is chock full of these and other nuggets of pop culture.   The book features a chapter about  Kodachrome esoterica. The Kodachrome name has appeared on a huge assortment of merchandise, and the book devotes an entire chapter to the subject.   Though out of production for years, the name Kodachrome is even recognized by a generation whose entire experience of photography is through their smartphones.
