Publishing

The commercial publishing industry ranges from large multinational conglomerates such as News Corp, Pearson, Penguin Random House, and Thomson Reuters to major retail brands and thousands of small independent publishers. It has various divisions such as trade/retail publishing of fiction and non-fiction, educational publishing, and academic and scientific publishing. Publishing is also undertaken by governments, civil society, and private companies for administrative or compliance requirements, business, research, advocacy, or public interest objectives. This can include annual reports, research reports, market research, policy briefings, and technical reports. Self-publishing has become very common.
Publishing has evolved from a small, ancient form limited by law or religion to a modern, large-scale industry disseminating all types of information.
"Publisher" can refer to a publishing company, organization, or an individual who leads a publishing company, imprint, periodical, or newspaper. Provided by Wikipedia
