Today, our phones go EVERYWHERE with us!  Nearly everyone I know has a cellphone (or, more accurately, a smartphone) and most people I know no longer have landlines.

Clearly, it wasn't always like that.  It wasn't until the early 2000s that cellphones became cheap and reliable enough for the average person to ditch their landlines.  In fact, for the first 50+ years following the invention of the phone, you couldn't just pick up the phone and call someone.  The operator had to make the connection for you.

Then, in the 1950s, that all started to change.  Communities were slowly converted to "dialing service".  Not a big surprise, when this feature was added, people needed to be trained to dial their phones.  Apparently, most of this training was done through movies like this one:

What I want to know is, if this film was made in 1954, where did people see it?  Was it on TV?  Or, did they heard people who were getting dialing service into movie theaters and MAKE them watch this 10 minute long masterpiece?
