The next stage in shopping was the transition from 'single-function' shops selling one type of good, to the department store where a large variety of goods were sold. As economic growth, fueled by the Industrial Revolution at the turn of the 19th-century, steadily expanded, the affluent bourgeois middle-class grew in size and wealth. This urbanized social group was the catalyst for the emergence of the retail revolution of the period. The first reliably dated department store to be established, was Harding, Howell & Co, which opened in 1796 on Pall Mall, London.
This venture was described as being a public retail establishment offering a wide range of consumer goods in different departments. This pioneering shop was closed down in 1820 when the business partnership was dissolved. Department stores were established on a large scale from the 1840s and 50s, in France, the United Kingdom and the US.
Stores are divided into multiple categories of stores which sell a selected set of goods or services. Usually they are tiered by target demographics based on the disposable income of the shopper. They can be tiered from cheap to pricey.
Some shops sell secondhand goods. Often the public can also sell goods to such shops. In other cases, especially in the case of a nonprofit shop, the public donates goods to these shops, commonly known as thrift stores in the United States, charity shops in the United Kingdom, or op shops in Australia and New Zealand. In give-away shops goods can be taken for free. In antique shops, the public can find goods that are older and harder to find. Sometimes people are broke and borrow money from a pawn shop using an item of value as collateral. College students are known to resell books back through college textbook bookstores. Old used items are often distributed through surplus stores.
Various types of retail stores that specialize in the selling of goods related to a theme include bookstores, boutiques, candy shops, liquor stores, gift shops, hardware stores, hobby stores, pet stores, pharmacies, sex shops and supermarkets.
Other stores such as big-box stores, hypermarkets, convenience stores, department stores, general stores, dollar stores sell a wider variety of products not horizontally related to each other.
