> has there been any discovery made with the help of a collider that found its way into an industrial product?
Yes. SLAC has an excellent public-lecture series that touches on industrial uses of particle colliders [1].
If you want a concrete example, "four basic technologies have been developed to generate EUV light sources:" (1) synchrotron radiation, (2) discharge-produced plasma, (3) free-elecron lasers (FELs) and (4) laser-produced plasma [2]. Synchrotrons are circular colliders. FELs came out of linear colliders [3]. (China has them too [4].)
We have modern semiconductors because we built colliders.
In the context of the article "collider" means intersecting particle beams, like in RHIC and LHC, which obviously involves rather low probability interactions, as opposed to accelerators which slam a beam into a dense target (like the SLAC accelerator). In a synchrotron light source you want the beam to circulate and specifically not collide with anything; they were developed from particle physics accelerators, of course.
