For Want of a Nail and TV

Robert Sobel's For Want of a Nail if If Burgoyne Had Won at Saratoga (POD at Saratoga) has glowing reviews from Ian.

On its TVtropes page, it claims " subtle example, but one reviewer noted that there are televisions before there are nuclear weapons, despite the interdependent nature of these technologies' development"

But these Wikipedia articles

Clearly shows not only mechanical television but CRTs before WW2!

So how are nukes and Television have interdependent development nature?
 
They are not interdependent inventions though some of the scientific knowledge needed to successful invent one is also needed to invent the other. You are correct, the TV predates nuclear weapons technology by quite a bit, commercial TV broadcasting dates from the experiments in 1928 at GE headquarters which was in Schenectady, NY at the time, today that same station still exists as WRGB Channel 6. General Electric did have quite a bit of theoretical work in the nuclear physics discipline nearby there, about 10 miles away, at Kesselring and Knolls Atomic Power Lab, but how much collaboration between different departments of GE there was back then I don't know. But neither discipline of science is dependent on each other. But with like a lot of technological advances in the US it helps if your timeline has a General Electric or equivalent, otherwise to muster the economy of scale and shear monetary requirements of R&D is going to be difficult and the advancement of science will suffer (same can be said of GM, IBM, and a few other companies).
