The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibition and rodeo in the world. It includes one of the richest regular-season professional rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003, with the exception of 2021 due to the effects of the COVID-19 pandemic. It was previously held in the Astrodome. It is considered to be the city's "signature event", much like New Orleans's Mardi Gras, Dallas's Texas State Fair, San Diego's Comic-Con and New York City's New Year's Eve at Times Square. In 2017, attendance reached a record high of 2,611,176 people and 33,000 volunteers. In 2007, the rodeo was deemed "the year of the volunteer." The event is 20 days long. It is kicked off by the Downtown Rodeo Roundup held near Houston City Hall, the Downtown Rodeo parade, and the ConocoPhillips Rodeo Run – a 10k and 5k walk & run and the World's Championship Bar-B-Que Contest. The show features championship rodeo action, livestock competitions, concerts, a carnival, pig racing, barbecue and the Rodeo Uncorked! International Wine Competition, shopping, sales and livestock auctions. Traditional trail rides, which start in different areas of Texas and end in Houston, precede the Rodeo events. The City of Houston celebrates this event with Go Texan Day, where residents are encouraged to dress in western wear the Friday before the rodeo begins. The rodeo has drawn some of the world's biggest recording artists, including Gene Autry, Beyoncé, blink-182, Selena Gomez, Keith Urban, Ariana Grande, Selena, Reba McEntire, Kiss, Kelly Clarkson, Demi Lovato, Charley Pride, Elvis Presley, Bob Dylan, Alan Jackson, REO Speedwagon, Brooks & Dunn, George Strait, Janet Jackson, Garth Brooks, Willie Nelson, Kenny Chesney, Bon Jovi, ZZ Top, Chris Stapleton, John Legend, Taylor Swift, and Lynyrd Skynyrd, among others. History Early years In the early part of the 20th century, Houston-area ranchers developed a new breed of cattle, the American Brahman, which was a blend of four breeds of cattle from India. The cattle were well-adapted to the hot, swampy conditions of the Texas Gulf Coast. In the early 1920s, James W. Sartwelle, a stockyard manager from Sealy, Texas, founded the American Brahman Breeders Association. Ranchers had no opportunities to show their cattle and raise awareness of the breed. Some attempted to show at the Southwestern Exposition and Livestock Show in Fort Worth, Texas, but they weren't allowed
