The first Integrated Circuit chips could have failed and the idea been abandoned as just another idea that didn't work. After that electronics stalls at the transistor level. Eternal 1950's technology.
The problem is that the integrated circuit was basically at "steam engine time" by the late 1950s, with many people proposing and working on the idea. If the first chips fail, they'll just take another approach--hell, that's what happened IOTL, with TI's chip design quickly falling out of favor for Fairchild's.
The reasonable way to find some kind of "sticking" is to look for cases where a "primitive" technology could be improved to the level where it wouldn't be worthwhile to replace it with a "more advanced" technology, like with the rocket example. For example, with the "no DVD" example, well, modern data tapes actually have a very high data storage density, much higher than even Blu-Ray disks, and there were various attempts to develop video tape standards that could have competed with DVDs, but they failed mostly because they came onto the market too late. Switch things around so that DVDs are delayed and advanced video tapes are, well, advanced, and you could very well end up with a universe where tapes are the standard for video data for at least quite a while longer. After all, the advantages of DVDs at that point would mostly be things like "random access" and "extra content," which aren't exactly a firm foundation for selling customers new, expensive equipment and new, expensive disks.
