Many companies have both B2B and B2C (business-to-consumer) elements, however many companies chose to specialise in B2B services or sales exclusively. A vast number of products and services sold are calculated to be B2B in nature, the popularity of this is often due to the sheer volume of sales and services related to B2B business.
