Whatever happened to the ready availability of sparkling/fizzy water (think Perrier) at retail outlets offering cold bottled beverages?

Several years back when Perrier was in their heyday, it seemed like fizzy water was as popularly available as plain water is today.
Where did it go?

In the Midwest USA I might, maybe, occasionally see Perrier for sale at a convenience shop. Usually that’s only if I’m traveling, and the outlet is on an interstate. Spot check of about 5 local outlets had no fizzy water.

I prefer sparking water over anything, and it’s not available. Some of the newer fountains seem to offer plain carbonated water. I hope it’s a trend!
