Marketplace from WikiPedia:

A marketplace is the space, actual or metaphorical, in which a market operates. The term is also used in a trademark law context to denote the actual consumer environment, ie. the 'real world' in which products and services are provided and consumed.

Wholesale marketing can take place at a market which primarily sells to traders such as caterers and small shopkeepers, rather than to members of the public, although members of the public are not necessarily excluded. London, England has several centuries old wholesale markets such as Smithfield Market and Billingsgate Fish Market.

The growing prevalence of internet access has enabled new markets to emerge online. Perhaps best known among these marketplaces is eBay, an enormous globally available auction house for products. The internet has also allowed less common marketplaces to thrive by connecting buyers and sellers from disparate locations. The formation of online marketplaces often occurs quickly in response to social or economic trends. Craigslist is another website that allows the public to trade goods and services. Internet marketplaces can further be categorized as B2B and B2C marketplaces.
