Being a New York City radio fan as well as a student of radio history, I purchased The Airwaves of New York, subtitled Illustrated Histories of 156 AM Stations in the Metropolitan Area, 1921-1996 as soon as I saw it while book browsing books on Amazon recently.
The first chapter of the book concentrates on the history of AM radio in New York City and briefly touches upon the history of FM radio and television.
The second chapter describes the history of each AM station that operated in New York City between 1921 and 1996... 156 stations from WAAM to WZRC. (The book was published 20 years ago, so the history after 1996 is not covered.)
The book is well illustrated with photos of the radio stations and the people who staffed the stations.
I enjoyed reading the book and recommend it.
