I call BS on this. The non-pouch detergents disappeared, that much I know. I strongly doubt people had stopped buying gel and powder. I suspect that some bright bulb at Johnson & Johnson or wherever did the math and realized that pouch margins were higher than gel and powder margins.
Fixed serving sizes force over-use. Lots of included water means extra volume and weight (perceived value) on the shelf. While powders allow measured use, and reduce turnover.
I buy 20lb boxes of cheap powder and they last for months. Hot water just doesn’t need that much help if you put some in the pre-wash too.
20 years ago in my country overuse of powder detergents was well known by all the manufacturers; this is when fixed serving sizes were developed as a way to contain the problem and they are also considered more convenient by most consumers. I was working in one of these companies at that time, so I know the subject pretty well.
I'll grant that the pods are often reasonably sized. My main complaint is that they don't provide any detergent to the pre-wash cycle. That can leave a lot of oil for the main wash to process.
There were a couple of very undesired side-effects that manufacturers hate because it was making the consumers angry:
1. Burning the color of clothes.
2. Irritating the skin (hand-was was very common, it still has some use cases even today).
Also there was a move around 2003-2004 to increase the concentration of automatic washer detergents, that was meant to decrease the transportation cost for manufacturers, but overuse was even riskier. I know it was done, somewhere before 2005 when I left that area of business, part of the solution was a big marketing campaign, another part was switching to liquid detergent with a measuring cup, also including a measuring cup in the package with the larger sizes. I don't know what happened later.
Depends on the household size and habits. Daily cooking for 4 or 5 people and sharing two other meals and the occasional baking can quickly fill up the dish washer, especially in those growing phases when the kids are eating like there is no tomorrow ;-)
The local supermarkets all stock literally one or two boxes on the shelf at a time, even though I know they have more in the back because as soon as I buy one it's put back on the shelf the next day. Something really funny is going on, I wouldn't be surprised if they had some contractual arrangement to artificially limit the amount that appeared in stock, to make it seem less appealing.
As someone who has worked in a grocery store I think you're reading way too much into it. They have priorities when stocking shelves but I think conspiracies by Big Detergent to get you to buy tide pods are low on the list.
