Machines to make frozen beverages were invented by Omar Knedlik in the late 1950s. The idea for a slushed ice drink came when Knedlik's soda fountain broke down, forcing him to put his sodas in a freezer to stay cool, which caused them to become slushy. The result was popular with customers, which gave him the idea to make a machine to help make a "slushy" from carbonated beverages. When it became popular, Knedlik hired artist Ruth E. Taylor to create a name and logo for his invention. She created the ICEE name and designed the original logo, which is used today. Early prototypes for the machine made use of an automobile air conditioning unit.
After a successful trial of ICEE machines in 100 stores, 7-Eleven in 1965 made a licensing deal with The ICEE Company to sell the product under certain conditions. Two of these were that 7-Eleven must use a different name for the product, and that the company was allowed to sell the product only in 7-Eleven locations in the US, a non-compete clause ensuring the two drinks never went head to head for distribution rights. 7-Eleven then sold the product that in 1966 became known as the "Slurpee" (for the sound made when drinking them). The term was coined by Bob Stanford, a 7-Eleven ad agency director.
The Slurpee machine has a separate spout, or spigot, for each flavor at the front of a tumbler or freezer, from which spigots they dispense their own Slurpees. When Slurpees were first introduced, the dispensing machine was located behind the counter, and the clerk dispensed the product. Common flavors are frozen Cherry, Coke, and Mountain Dew. But new flavors are introduced regularly. In the Slurpee's early history, flavors rotated much more frequently than today. Slurpee flavors were given novelty names such as Pink Fink, Adults Only, Moonshine, Kissin' Cousin, Gully Washer, Sticky Icky, and Redeye.
In 1990, Dallas-based Southland Corp., 7-Eleven's founder and US operator, went bankrupt, but Seven-Eleven Japan, and its parent Ito-Yokado, bought 70% of Southland in 1991 for $430 million and quickly launched renovations of the US stores. As a result, the US chains became more efficient, though 1,218 stores closed. Following the Japanese model, the new 7-Elevens set up a weekly system to monitor inventories to ensure popular items are always in stock.
Canadians purchase an average of 30 million Slurpee drinks per year. Manitoba was crowned the Slurpee Capital of the World for the nineteenth year in a row in 2018. 7-Eleven stores across Winnipeg sell an average of 188,833 Slurpee drinks per month. The rest of Canada sells an average of 179,700 per month, which makes Winnipeggers the world leader of Slurpee sales. Unlike their counterparts in America, Canadian Slurpees do not contain yucca extract which gives it the airy consistency American Slurpees are known for. In Mexico, the Slurpee was renamed Frözt. 6.6 million Slurpee drinks are sold in Australia each year.
The Diet Pepsi flavor uses sodium caseinate as an anti-freezing agent (sugar is a natural antifreeze in other flavors) which only gives it the status of kosher dairy. The Piña Colada, Twizzler Strawberry, Tropicana Grape Wild Strawberry, and Monster Black flavors are not kosher. They have an updated list on the CRC website.
In 1965 - 66, Icee transitioned to Slurpee in 7-Eleven stores and sales. By the spring of 1967, Slurpee machines were in all 7-Eleven stores.
In 1967, Top 40 AM radio stations were losing market share to FM stations. DJs were desperate to gain audience attention. Slurpee was a kid / teen / young adult product, the main AM radio audience. The Stanford Agency created a "media blitz" to launch Slurpee and flew agency staff to all Top 40 markets with 7-Eleven stores to introduce Slurpee and the comedy commercials with funny voices and sound effects that told stories about the Strange Things That Happened To People Who Slurp. The agency backed the Slurpee launch with a very large media budget. DJs used "drops" or snippets from the "crazy" commercials in their programs to gain audience share. The campaign became an AM radio sensation.
The Stanford Agency followed the Strange Things launch with a campaign that threw away product names like lemon-lime, cola or what have you, and instead created 26-weeks of :60 second commercials about Slurpees with Funny Names like Sticky Icky, Redeye, Moon Shine, Pink Fink, Adults Only, Kissin Cousin, and Gully Washer. These commercials were even more popular. Each flavor had a pin associated with it. There were pins made for the flavors There was also a generic pin that simply stated "I have Slurped".
In 1968, the Official Slurp Hat was offered.
In 1970, 7-Eleven released a 45 RPM 7" single record entitled "Dance the Slurp" that was given away with Slurpee purchases. The dance side was written by Tom Merriman, one of the fathers of radio jungle production. The B-side was a comedy bit detailing "strange things" that happen to people who "slurp" at 7-Eleven. The record is considered highly collectible today. In 1999, "Dance the Slurp" was sampled by DJ Shadow and Cut Chemist for their Brainfreeze mix album.
Slurpee became the top selling 7-Eleven product and kids / teens / young adults came in regularly for the latest "flavor" with less and less promotional expense. After Funny Names, the next innovation was Slurpee Cups.
In 1972, Baseball Slurpee Cups, plastic cups with illustrations of favorite players including Johnny Bench, Pete Rose and others.
In 1973, Baseball Slurpee Cups, with illustrations of current stars and early players like Honus Wagner.
In 1973, the DC Comics Super Hero Cups, a 60 cup series.
1973 Endangered Species Cups – Congress passed the Endangered Species Act (ESA) on December 14, 1973. This triggered 7-Eleven making an advanced of $250,000 representing 1-cent from the sale of more than 2-million Endangered Species Cups to the National Wildlife Federation (NWF) who purchased Bald Eagle habitat. The transfer of land to the U.S. Government and U.S. Fish and Wildlife Service took place on December 19, 1974 and came to be known as the Carl E. Mundt National Wildlife Refuge.
1975, the Marvel Series, a 60 cup series.
1977, the Marvel "Panoramic" Super Hero series.
In 1994, 7-Eleven sought to remake Slurpee's "brain freeze" campaign targeted to the adolescent MTV audience. The creative directors assigned the task of creating four new commercials to the Brothers Quay, and Boston-based Olive Jar Animation. Known for their bizarre aesthetic and influence in the stop-motion animations industry, the Quays based their "brain freeze" ad on a late 19th-century photograph of a female contortionist. In the commercial, a curtain reveals the contortionist balancing on two chairs, bending over backward to sip a Slurpee. She falls victim to "brain freeze" and turns into an ice cube.
Starting in 1995, free Slurpee coupons have been made available through "Operation Chill" for US police officers to distribute to children.
In 1998, 7-Eleven launched Slurpee lip balm to the market. Other "Slurpee-flavored" products have included Slurpee gum, which had a liquid candy center.

Since July 7, 2011, 7-Eleven has partnered with Cinemark Theatres marking the first time Slurpees are sold outside its parent franchise. 32 theatres were chosen in Houston, Texas; Dallas, Texas; and Portland, Oregon. This marks the first reappearance of the Slurpee brand in the Houston metro area since 1990 (all 7-Elevens in the Houston area were sold to National Convenience Stores that owned Stop-n-Go - all Houston-area 7-Elevens were rebranded as Stop-n-Gos until Diamond Shamrock acquired the franchise in the late 1990s, now part of the Valero conglomerate of crude oil refineries and retail convenience stores most commonly operated under the Valero brand with generic names, though some Texas-area stores retained Corner Store branding held over from the Valero purchase of Ultramar Diamond Shamrock in 2001.
In Australia on September 21, 2011, customers could bring in their own cups (or container, regardless of size) and fill it full of Slurpee for only $2.60 (a portion of the price of a Super Slurpee) as long as it would fit through a cutout hole limiting the size. This did not stop people from receiving up to and above 5 liters of Slurpee for less than the price of a Super Slurpee. This event was known as Bring Your Own Cup Day.
Since 11 April 2015, Bring Your Own Cup Day in U.S locations originally occurred once annually; now semi-annually since 2016. Slurpee fans could come in and enjoy any size cup, that fit through the cutout hole, for only $1.49 the first 2 years. This promotion occurred again on 19–20 August 2016 in honor of the Slurpee's 50th anniversary. It returned on 19–20 May 2017, but the price was $1.50 plus tax, and returned once more on 18–19 August.
