Our first advertisement for advertising-funded television companies comes from the Commercial TV Yearbook.  The Commercial TV Year Book and Directory, to give it its formal title, was the advertisers annual bible.  Not only could you get company addresses, advertising rates and film formats, but also independent animators, jingle writers and the home addresses of popular stars and their agents.

If you wanted to advertise on television (and hadn't already been contacted by ABC's famously pushy sales department) you could quickly make a list giving you the phone numbers for everything you would need to advertise.

Outside of the main directory pages, the big TV companies of the time also advertised, letting you know where they were, where they served and who to call.  ABC in 1957 is boasting that 6 out of 10 of the population is served by ABC (most regional companies had yet to come on air).  They boast about a new phenomenon - people with a disposable income and a good education, a post-war section of society where trying new things was something they were willing to do.  These people ABC dubs 'the new middle classes', and helps ignite the fuse that would lead those classes to becoming the rulers of the country in 2 generations.
