Haha this is a very intriguing question, Merfish. So i'm obliged to help you. In 1958, Malaco, a Swedish confectionery manufacturer, expanded its business by exporting a few of their products to North America. Various licorice ribbon and licorice lace candies were the first products to be exported. Malaco's export trade grew and in the late 1960s and early 1970s, Swedish Fish and Swedish Berries (identical in composition but in the shape of berries) were developed specifically for the North American market. Today the Swedish Fish consumed in North America are made in Hamilton, Ontario, Canada by the Cadbury Adams Company. The fish are distributed in the U.S. by Cadbury Adams USA in Parsippany, New Jersey. In the UK Swedish Fish can be found in IKEA's Swedish Food section, including the salmiak The Gummi Bear originates from Germany where it is popular under the name About this sound Gummibär (help·info) (rubber bear) or About this sound Gummibärchen (help·info) (little rubber bear). Hans Riegel of Bonn invented bear-shaped sweets[citation needed] and started the Haribo company in 1922, which produced and introduced its Gold-Bear product in the 1960s. Trolli is another gummi candy manufacturer and the first to introduce gummi worms in 1981. So its obvious to see Gummy Bears were invented first, followed by the Swedish Fish. I got my info from www.wikipedia.com :]

I think Swedish Fish started it all, only 'cause I remember them as a kid, and Gummy Bears and Worms not until I had kids.
