CNN/Money has released a cool, less-than-two-minute video that traces the evolution of the American home--starting in 1973, when the median new single-family home was 1,525 square feet. By the end of the decade, fireplaces and air conditioning units had become commonplace.

The video traces the trends that have shaped the single-family world. For instance, the 1980s started with most homes being heated by electricity, and ended with most homes being heated by gas. The proliferation of vinyl siding in the early 90s displaced wood exteriors. The fireplace becomes much less common by the early 2000s,

And by 2013, the average single-family home had grown to 2,384 square feet in size.
