a maker of model cars, in 1993. In 1984 Tyco produced its own interlocking brick product, "Super Blocks". Super Blocks were compatible with LEGO, and were made following the basic LEGO patent's expiry in 1978. LEGO attempted to halt the production of Super Blocks in a lawsuit, which was later won by Tyco in 1987. Tyco's musical toys of the late 1980s and early 1990s included the Tyco Hot Lixx and Tyco Hot Keyz, an electronic guitar and keytar respectively. Across the late 1980s and early 1990s, some of Tyco's most popular toys came from their Radio Control division, with over 100 different models manufactured primarily through their partnership with Taiyo RC (Japan). In the 1992 Tyco Catalogue used in industry toy fairs to sell and promote products to major retail buyers, the first 20 pages was consumed by their lineup of radio control toys for the year. These products and their manufacturing deal with Taiyo became so important that they took a significant ownership stake in the company, and began to strongly influence the features and design of the vehicles. This resulted in all Taiyo models, both those sold under the Taiyo brand in Japan and worldwide, and those sold by Tyco changing from predominantly realistic models of actual vehicles (such as the 1988 Lamborghini Countach and 1989 Porsche 962) to less realistic products such as the 1994 Tyco Triple Wheels, 1993 Tyco Python, and 1997 Tyco Tantrum. In the 1990s, the company also branched out with other toys such as airplanes. It made a hit in 1991 with their Disney's Little Mermaid dolls that were released in conjunction with the movie. Tyco's Sesame Street line increased dramatically in popularity in 1996, when the plush doll Tickle Me Elmo became the most sought-after toy of the Christmas season. Defunct When Tyco was purchased by Mattel on March 27, 1997, it was the third-largest toy company in the United States. The brand survived into the 2000s and beyond as the Mattel Tyco R/C division, while much of the Sesame Street line, Magna Doodle, and the View-Master were transferred to the Fisher-Price division. On February 23, 2019, Terry Flynn announced that Tyco was now a registered trademark of his Harden Creek Slot Cars, LLC.
