Trade magazine

[1] The collective term for this area of publishing is the trade press.

[3] As digital journalism grew in importance, trade magazines started to build their presence on the internet.

To retain readership and attract new subscribers, trade magazines usually impose paywall on their websites.

Trade publications include targeted advertising, which earns a profit for the publication and sales for the advertisers while also providing sales engineering–type advice to the readers, that may inform purchasing and investment decisions.

[6] For printed publications, some trade magazines operate on a subscription business model known as controlled circulation, in which the subscription is free but is restricted only to subscribers determined to be qualified leads.
