B2C refers to the market when businesses sell goods and services directly to their customers and there is no middle man involved. The companies selling directly to the end-user can be referred to as B2C companies.
B2C acquired ubiquity after the website blast of the last part of the 1990s when it was chiefly utilized by online retailers. B2C has a global reach for the end-users, so the small business running from the home can sell the customers of another side.
Eating out in the restaurants, paying for the movies, shopping at the mall are some examples of the B2C marketplace.
