VHS was not driven by porn, and neither was video compression.
VHS adoption was driven by the fact that time shifting content was a godsend that people loved. This is a huge reason VHS beat betamax, because you could fit more football games on the VHS, even in it's abysmal longest recording quality. People bought VHS recorders well before anyone was releasing ANY media on VHS.
Name a single video compression codec or ASIC that was produced by or for a porn company. Math geeks made compression codecs well before they were viable for software encoding on general purpose computers, and then set top box manufacturers drove the adoption and development of ASICs that could actually use those codecs.
What porn HAS driven is innovation in video streaming platform UI. Youtube has stolen every nice feature it has from Pornhub, who usually deployed them years earlier.

I think you're quibbling over what "driven by" means. Porn was not the origin of any of these, but there's pretty good evidence that its popularity played a significant role in the adoption of technologies ranging from the printing press to photography to streaming video. VHS being cheaper and recording longer caused it to be adopted by the porn producers, which resulted in much more porn being available on VHS, which tilted things in its favor. (Well, that and Sony's ambivalence towards porn on Betamax.) Geeks indeed liked to work on compression, but nobody would have cared without an application for it, and a big chunk of early internet traffic was porn. The difference between waiting 5 vs 30 minutes for a download is pretty influential. Devices with hardware acceleration, including ASICs, were popular because people had applications for them, and a solid percentage of those applications were porn.
I grew up during the development of all of these technologies. I've never been one for watching porn, but even then, it was pretty clear at least in my environment that porn was very influential. Hints and tricks to download and decode compressed video spread very rapidly through word-of-mouth networks, specifically for porn content.
Earlier, the same thing happened for stills, which were more my thing so I have firsthand knowledge. Heck, the standard test image was Lena—what showed up in the research papers was tame, but the extra 2/3 of the image below that is the reason why that was the most popular test image. https://en.wikipedia.org/wiki/Lenna
