"The cost of the service, amounting approximately to $3,500,000 per annum, is assessed upon the members and becomes a part of their costs of operation, to be recouped, presumably with profit, through the publication of their several newspapers. Under complainant’s by-laws each member agrees upon assuming membership that news received through complainant’s service is received exclusively for publication in a particular newspaper, language, and place specified in the certificate of membership, that no other use of it shall be permitted, and that no member shall furnish or permit any one in his employ or connected with his newspaper to furnish any of complainant’s news in advance of publication to any person not a member. And each member is required to gather the local news of his district and supply it to the Associated Press and to no one else."
