Yes, none of the 'resurgence of film' has resulted in any of the former minilabs resuming developoment (speaking of Walgreens, Costco, and the like.)
There are of course speciality labs, I have used several, such as Indie Film Lab, the Darkroom, Dwayne's, NCPS, Pro Photo Connection, Miller's Lab, and others. These labs have been around a while, and spent much time and energy building their internet business to support scanning services, as well as development. As local labs closed, these speciality labs filled the gap. But generally speaking they don't cater to the casual shooter/student shooter.
Locally for me, there are only two labs that remain, one being Precision Camera who advertises on this site, and the other being Holland Photo.
I was, in fact, the person who established the relationship between Precision with this site, and started the develop/scan promotion nearly a decade ago, that is still in place. Precision was nearly about to shutter their lab at the time, and one way to help keep it open was to seek out internet business.
Precision has not developed anything other than C41 in many years, they farm out their B&W and E6. But at least their C41 and scanning business still exists.
There had to be places for customers to go, once Walgreens/CVS/Costco (and many others) all closed down their local labs, and these internet suppliers stepped up to fill the gap.
One of the specialty offerings of these labs, is professional scanning. Local labs simply did not have the expertise for professional color correction for wedding shooters, for example. That service is a major part of why the internet labs exist.
There has been no increase in the number of labs, it's actually been on a very steady continuing decline. This does not necessarily mean that business at individual labs is down, however. If one were to speak to a few of these internet labs, they might all report increases in business. It doesn't necessarily follow that the increase in business is due to an increase in the number of film shooters, however.
