My thoughts?
Well, why were they built, and used starting in the early part of the war?
1. Every army prepares to fight the war that it just finished, not the one that's coming. So, at the beginning of the war, they mostly had long-guns on hand, KAR-98, #3/#4 Enfields, Springfields, some Garands, etc.
2. Germany kicks butt with their Blitzkreig tactics, and people start to recognize the fire-power boost that having individual machine-guns provides (SMG's, LMGs, etc) (Recall that at the end of WWI, the planned use of the Pedersen device was kept secret, and they ended up destroying them eventually)
3. With the loss of both trained troops, weapons, and equipment, and the shock of the German Blitzkreig, a shift in doctrine to include personal, portable automatic weapons was inevitable.
4. The need to create a LARGE number of weapons in a SHORT period of time led to the mass production of the Sten, M-3, etc type of SMG's, but their limitations were eventually discovered in the crucible of battle in the last year of the war by the allies. (Truly, the allies did not utilize their weapons much until after invading europe in 1944.)
5. The lesson that pistol caliber SMG's are not the best weapon for infantry combat was learned by the Germans in the blitzkreig, and re-inforced in Barbarossa. (This is a lesson that was re-learned by the Israelis with their Uzi....hence the existance of the Galil.)
6. The Germans took those lessons, and created the SturmGewehr.
7. Following the war, the other major powers took a page from the books of Germany's war experience, and headed down similar paths, with varying degrees of success.
So, those are my thoughts....there's a lot more that could be said as to why and how, but there's some of my points that I can come up with off the top of my head.
