There are several types of markets where buyers and sellers can meet to exchange goods and services. Markets can exist in physical locations where buyers and sellers gather, or they can exist virtually over communication channels like telephone lines, online, or through email. The main types of markets are consumer markets, business markets, global markets, and non-profit/government markets. Consumer markets involve individuals and families buying goods and services for personal use, while business markets involve organizations buying goods and services for business purposes other than personal consumption. Global markets consist of international transactions conducted across national borders, and non-profit markets involve selling goods and services to charitable organizations that have lower purchasing power.
