Short PSA Made By AT&T In 1936 To Help Familiarize Viewers With Dial Telephones

If you wanted to make a non-local call back in 1936 you typically had to speak to a switchboard operator, who would connect your call to a number that began with exchange letters related to the location you were calling.But as phone technology improved the old system was phased out, replaced with the ability to dial phone numbers directly via automatic exchange systems and rotary phones, which totally freaked some people out.
Thankfully, AT&T was there for folks who were frightened by all that newfangled telephone technology, alleviating their concerns with this short PSA that explains how the dial telephone works.
