Ice industry ruined.

Ice houses were great and provided employment for people.  Someone came along and destroyed the thriving industry.
It might be one of the world's most transformative inventions when it comes to our diets, but the refrigerator was initially met with a frosty reception. Although ice houses such as the one pictured were relatively popular with the upper classes, everyday people relied on techniques such as pickling to preserve their food.
When electric refrigerators were first brought to market in the early 1900s, they were dismissed as noisy, expensive, and difficult to maintain.
To make matters worse, ice was America's second-biggest export after cotton at the time, and critics widely slammed the refrigerator as they believed it would harm the domestic ice industry.
However, following a series of developments from the likes of General Electric, refrigerators became much more practical for home use. Consumers began to "warm up" to the world of electric refrigeration and never looked back.
