Candidate passages:
Since at least 1978, a variation called the "puffy taco" has been popular.
"Henry's Puffy Tacos", opened by Henry Lopez in San Antonio, Texas, claims to have invented the variation, in which uncooked corn tortillas (flattened balls of masa dough) are quickly fried in hot oil until they expand and become "puffy".
Fillings are similar to hard-shell versions.
Restaurants offering this style of taco have since appeared in other Texas cities, as well as in California, where Henry's brother, Arturo Lopez, opened "Arturo's Puffy Taco" in Whittier, not long after Henry's opened.
Henry's continues to thrive, managed by the family's second generation.
Kits are available at grocery and convenience stores and usually consist of taco shells (corn tortillas already fried in a U-shape), seasoning mix and taco sauce.
Commercial vendors for the home market also market soft taco kits with tortillas instead of taco shells.
The breakfast taco, found in Tex-Mex cuisine, is filled with meat, eggs, or cheese, with other ingredients.
The tacodilla contains melted cheese in between the two folded tortillas, thus resembling a quesadilla.
The pop duo PUFFY did a commercial for Morinaga Milk. 
Mighty Taco is known for having unusual, somewhat surreal TV advertisements, created by Paragon Advertising.
These commercials are also designed to be permissible on commercial-free public television stations, and WNED-TV airs the advertisements when promoting Mighty Taco as a supporter.
Their radio advertisements are usually parodies of popular culture, such as prescription drug commercials, with a non sequitur at the end of the commercial directing listeners to Mighty Taco. 
Choco Taco is a brand of dessert food resembling a taco, consisting of a sugar cone–like taco shell waffle cone, reduced-fat vanilla ice cream, artificially flavored fudge, peanuts, and a milk chocolate coating.
The product was invented in Philadelphia in the 1980s by Alan Drazen, Senior Vice President of the Jack and Jill Ice Cream Company, but was first rolled out in 1984 when it became popular in mobile vending trucks and convenience stores.
It made its first appearance in supermarkets nationwide by Good Humor-Breyers in 1996 as "America's coolest taco", at the Supermarket Industry Convention in Chicago, Illinois.
The "Choco Taco" is marketed under Klondike brands, marketed as "The Original Ice Cream Taco".
The brand is sold by Good Humor-Breyers, a division of Unilever.
In 1998, Unilever introduced the Choco Taco to Italy and 1999 to Sweden with the name Winner Taco.
In 2000 the Winner Taco was retired from the Italian/Swedish market.
After two years of campaigning by Taco fans, on January 2014 Algida announced on their Facebook page the return of the Winner Taco in Italy.
GB Glace selling the ice cream in Sweden has also re-introduced the ice cream in 2014.
In 1999, the company improved the product, incorporating a shell which stayed crisper, and introduced new packaging.
The same year, the company introduced a Klondike Cookies & Cream Choco Taco, containing cookies and cream ice cream and covered with cookie pieces.
Choco Tacos have also been sold at and Taco John's restaurants, from ice cream trucks outside the facility.
