The market for Tech Pan was just not there! There was no profit margin for it.

“The photographer must determine how he wants the finished print to look before he exposes the negative.
Before releasing the shutter, he must seek 'the flame of recognition,' a sense that the picture would reveal
the greater mystery of things...more clearly than the eyes see." ~Edward Weston, 1922.
It was good in 4x5 if you wanted to enlarge to several feet on a side and not see grain from close viewing.
It's main claim to fame was having such fine grain a 35mm negative, if shot very carefully with superb glass, could produce a print to rival one from 4x5 on conventional film. Maybe larger formats becoming more affordable as digital became more popular helped do it in.
I never cared for it. Weird spectral response, special developer needed, and painfully slow. If I could tolerate the speed I'd rather have used APX 25 which was quite fine grained enough for me. But some people did love it, true enough.

I thought it was the blue and magenta you could get out of it in some images so it wasn't truly B&W which to me is really the appeal, I wish I could get my hands on the developer. I have 2 rolls of 120 and 8 rolls of 135 and I'd love to get some great shots even if its fairly old.

I have a Modern Photography magazine, November 1982, (OMG, 30 years!) which has an article quoting Kodak as delivering "4x5 quality with a 35mm camera". It was in the form of the Tech Pack 2, two rolls of Tech Pan with sufficient Technidol LC developer. The article describes Technidol as "Kodak's new packaged version of POTA developer" which they say up until then was "...a formula which must be concocted from scratch", also referring to "mixing and storage difficulties" when compounding it yourself. Makes it sound like POTA was a PITA...
They compared photographs from the kit with 4x5 Tri-X and Plus-X, both in D-76, and while not their equal, it did give them a decent run of it. They also compared it to other 35mm B&W films-Ilford Pan-F in Perceptol,. Panatomic-X in Microdol-X, and Agfapan 25 in Atomal, which all rendered detail about as well, but with more grain.
Related to Roger's comment, they mention Tech Pan's "extended red sensitivity" which will of course lightens reds.

I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.

I want to hear more about the Tech Pan stash referenced above. I have my own stash, mostly 35mm and 120 and technidol. Wish I had some 4x5. what a great film. I shot piles of that back in the 90s. Many bulk rolls.... Fortunately it keeps great.
I don't know anything about Techpan, but the Adox Silvermax film is very good for enlarging. I have had very good luck having it enlarged to 11x14 without noticeable grain. The blufire police film is supposedly just as good for extreme enlarging, but I am supporting Adox.
Recently I tried Silvermax - it is great film, I printed 30x40cm print and wonder why people complain about 35mm format . But it is not comparable with Kodak TP. Only thing that I could compare to TP (speaking about grain size) from todays films that are still in production is Adox CMS 20.
