What's the history behind outdoor and indoor PlayPlaces??

[JohnRamone96]

I know this is a subject that doesn't seem to be brought up much, but I am wondering what the history is behind fast food restaurant PlayPlaces?? At McDonald's, Burger King, Carl's Jr, and Chick fil A. I know some areas of the country and certain restaurants phased out of these playgrounds years ago and there are some that still have them and still have as many as they did at their peak, and even McDonald's still builds new locations with PlayPlaces. Why did a majority of Burger King restaurants decide to do away with outdoor playgrounds in 2008, while the indoor ones weren't affected by that decision and there are still a few Burger Kings to this day that have outdoor playgrounds? And there is no article explaining why?? The Carl's Jr franchises in my town of Cameron Park, nearby Folsom(indoor one), Citrus Heights(indoor one), and Roseville decided to do away with their PlayPlaces in 2021, while the locations in Auburn (now closed) and Galt with outdoor playgrounds kept them. Do they strategically choose what playgrounds to keep.

Here's my article explaning the history of Carl's Jr playgrounds: https://haydenbusinessblog.blogspot.com ... coast.html
Here are the lists of McDonald's, Carl's Jr and Burger King playgrounds:

Just wondering about how this segment is run. Do indoor playgrounds generate much more business or do outdoor ones have just as much?? Why didn't Carl's Jr get more into the indoor playgrounds in the 2000s??
