it unveiled a new slogan: "Saving people money so they can live better lives". Walmart has also made steps to appeal to more liberal customers, for example, by rejecting the American Family Association's recommendations and carrying the DVD Brokeback Mountain, a love story between two gay cowboys in Wyoming. Sales of guns and ammunition Walmart stopped selling handguns in all U.S. states, except for Alaska, in 1993. In 2018, Walmart stopped selling guns and ammunition to persons younger than 21, following a similar move by Dick's Sporting Goods on the same day. In the same year, Walmart stopped selling military-style rifles that were commonly used in mass shootings. As of 2019, Walmart was a major retailer of firearms and ammunition. In 2019, after 23 people were killed in a mass shooting at a Walmart store in El Paso, Texas, Walmart announced that it would stop selling all handgun ammunition and certain short-barreled rifle ammunition. The company also announced that it would stop selling handguns in Alaska, the only state where the company still sold handguns. The move was expected to reduce Walmart's U.S. market share in ammunition from around 20% to around 6–9%. Walmart also stated that it was "respectfully requesting" that customers not openly carry weapons in Walmart stores, except for authorized law enforcement officers. Following the fatal police shooting of Walter Wallace Jr. in October 2020, Walmart temporarily removed gun and ammunition displays in thousands of stores across the U.S. from sales floors, grounding their reason in concerns of civil unrest. Company spokesman Kory Lundberg said in a statement that "We have seen some isolated civil unrest and as we have done on several occasions over the last few years, we have moved our firearms and ammunition off the sales floor as a precaution for the safety of our associates and customers." Firearms and ammunition will still be available for purchase on request, but the duration of the removal of both from the sales floor remains undetermined. Technology Open source software Many Walmart technology projects are coded in the open and available through the Walmart Labs GitHub repository as open-source software under the OSI approved Apache V2.0 license. 141 public GitHub projects are listed. During a migration of the walmart.com retail platform to Facebook React and Node.js, the Electrode project was created to power the e-commerce platform which serves 80 million visitors per month and 15 million items.
