The city is probably best known for the 1941 big-band swing song "Chattanooga Choo Choo" by Glenn Miller, but it has grown significantly since its days as a railroad hub and industrial center.

Chattanooga is the corporate headquarters and home of Olan Mills, Rock Creek Outfitters, Krystal, CBL & Associates, Chattem, Covenant Transport, U.S. Xpress, Inc (the 4th largest trucking company in the U.S.), National Model Railroad Association, UnumProvident, The Chattanooga Bakery (home of the Moon pie), and Miller Industries, the largest tow truck manufacturer in the world. Following the city's industrial decline, many businesses in the banking and insurance industries set up operations in Chattanooga. The city is home to large branch offices of Cigna, Blue Cross, AT&T and UBS. In addition to the above, other major employers are the Tennessee Valley Authority (TVA), ALSTOM Power, Inc., Erlanger and T.C. Thompson's Children's Hospital, and the Hamilton County Board of Education.
The city boasts the most productive affordable housing program in the nation. Chattanooga is notable for leveraging development funds through effective public private partnerships, and has significant civic involvement. It was one of the first US cities to effectively use a citizen visioning process to set specific long-range goals to enrich the lives of residents and visitors.
In addition to corporate business interests, there are many retail shops in Chattanooga, both downtown and in the outlying neighborhoods. There are three shopping malls in the area: Northgate Mall in Hixson, Eastgate Town Center in Brainerd, and Hamilton Place Mall in East Brainerd. There is also a large outlet mall downtown.
Originally founded by John Ross as Ross's Landing in 1816 as a center for Cherokee trade, it was renamed Chattanooga in 1838 after their departure on the Trail of Tears. During the American Civil War on November 23, 1863, the Battle of Chattanooga III began when Union forces led by General Ulysses S. Grant reinforced troops at Chattanooga and counter-attacked Confederate troops. The next day the Battle of Lookout Mountain was fought near the town. These were followed the next spring by the Atlanta Campaign, beginning just over the nearby state line in Georgia and moving southeastward.
In more modern times, the city has received national recognition for the renaissance of its once dilapidated downtown and redevelopment of its riverfront. An early cornerstone of this project was the restoration of the historic Walnut Street Bridge, which is now the world's second-longest pedestrian bridge behind the Shelby Street Bridge in Nashville, Tennessee.
In 1935, as well as from 1993 to 1995, Chattanooga hosted the National Folk Festival
