This sentence was put forward by Lenin at the end of19th century. At that time, with the rise of the socialist revolution and the arrival of the proletariat on the historical stage, newspapers became an important tool for revolutionary propaganda and organization. Newspapers can not only popularize socialist ideas and revolutionary ideas through propaganda, but also organize workers' movements and revolutionary actions.

Lenin believed that the function of newspapers is not only to publicize and encourage, but more importantly to organize the masses. He pointed out that newspapers can coordinate actions, unify thoughts and strategies, and organize actions such as assembly, strike and revolution. Therefore, Lenin believed that newspapers were the "collective organizers" of the socialist revolution.

In a word, Lenin emphasized the important role of newspapers in the socialist revolution, that is, to make contributions to the revolutionary cause through propaganda, agitation and organization.
