I found the earliest citation for "jimmies" (1940s), but I'm hoping to do better when ProQuest finishes digitizijng the Boston Globe.
"Sprinkles" can be black or multi-colored. They're usually put on ice cream cones. Some Europeans call them "hundreds and thousands" or even "mice."
Sprinkles (sometimes known as "jimmies" or "hundreds-and-thousands"; see below) are very small pieces of confectionery used as a decoration or to add texture to desserts – typically cupcakes, cookies, doughnuts, ice cream, and some puddings. The candies, which are produced in a variety of colors, are usually too small to be eaten individually and are in any case not intended to be eaten by themselves, being nearly flavorless. In the Netherlands, chocolate sprinkles, or "hagelslag," are used as a sandwich topping for sandwiches with sweet contents; this is also common in Belgium and Indonesia, once a colony of the Netherlands.
Sprinkles can be most commonly found on cupcakes, being that cupcakes generally have more frosting and less diameter than cakes. However, all sprinkles generally require frosting for which to stick onto.
Dutch hagelslag was first invented in 1936 by Gerard de Vries for Venz, a Dutch company made popular by said treat. Several letters to Venz from a five-year-old boy, H. Bakker, asking for a chocolate bread topping, inspired and prompted de Vries's development of sprinkles. After much research and venture, de Vries and Venz created the first machine to produce the tiny cylindrical treats. They were named "Hagelslag" after their resemblance to a weather phenomenon prominent in the Netherlands, hail.
Popular terminology tends to overlap, while manufacturers are more precise with their labeling. What consumers call sprinkles covers several types of candy decorations which are sprinkled informally over a surface rather than placed in specific spots. Sanding sugar; crystal sugar; nonpareils; silver, gold, and pearl dragées — not to be confused with pearl sugar (which is also sprinkled on baked goods); and hundreds-and-thousands are all used this way, along with a newer product called "sugar shapes" or "sequins". These latter come in a variety of shapes for holidays or themes, such as Halloween witches and pumpkins, or flowers and dinosaurs.
The Brigham's Ice Cream Company claims that "Jimmies were first developed by Just Born Candy Company, which was founded by Samuel Born, who immigrated to the US from Russia around 1910 ... Born ... decid[ed] to accredit the name to the producer, Jimmy Bartholomew. The new product was named JIMMIES, which is still a trademarked name ...."

Those little chocolate thingees you ask the guy at the ice-cream store to put on top of your cone. The multi-colored ones are "sprinkles."
Here is some history:
Back in the 1930s, the Just Born candy company of Bethlehem produced a topping called chocolate grains. The man who ran the machine that made these chocolate grains was named Jimmy Bartholomew.
"Thus, his product became known as jimmies," said Ross Born, the chief executive officer. He was told this story by his grandfather and company founder, Sam Born. Just Born registered jimmies as its trademark, and continued producing jimmies until the mid-1960s - which is why the name was so popular here.
The trademark expired and soon after, Just Born stopped making jimmies.
This account, however, has been disputed.
The Boston Globe investigated the origin of jimmies last winter after a reader inquired about a rumor that the term originally was racist - the idea being that some people refer only to chocolate ones as jimmies, and rainbow ones as sprinkles. Perhaps, the reader surmised, the word descended from Jim Crow.
The Globe found no evidence of this, but did cite a commentary in 1986 on National Public Radio by the late Boston poet John Ciardi, who claimed: "From the time I was able to run to the local ice cream store clutching my first nickel, which must have been around 1922, no ice cream cone was worth having unless it was liberally sprinkled with jimmies."
Ciardi, the Globe said, "dismissed Just Born as claim-jumpers looking to trademark someone else's sweet inspiration." His jimmies had come first.
The truth may never be known.

The ice cream cone is 50 years old, but it will never be middle-aged.
Chocolate, vanilla, strawberry, maple walnut, pistachio, lemon sherbet, fudge whirl or cherry ripple, it will make anyone feels a little giddy and a lot younger. Jimmies or not, its magic stays the same.
