California Code, Business and Professions Code - BPC § 25500.1

(a) The listing of the names, addresses, telephone numbers, email addresses, or Internet Web site addresses, or other electronic media, of two or more unaffiliated on-sale or off-sale retailers selling beer, wine, or distilled spirits produced, distributed, or imported by a nonretail industry member does not constitute a thing of value or prohibited inducement to the listed on-sale or off-sale retailer, provided all of the following conditions are met:

(b) For the purposes of this section, “nonretail industry member” is defined as a manufacturer, including, but not limited to, a beer manufacturer, winegrower, brandy manufacturer, rectifier, or distiller of alcoholic beverages or an agent of that entity, or a wholesaler, regardless of any other licenses held directly or indirectly by that person.

(c) The Legislature finds that it is necessary and proper to require a separation among manufacturing interests, wholesale interests, and retail interests in the production and distribution of alcoholic beverages in order to prevent suppliers from dominating local markets through vertical integration and to prevent excessive sales of alcoholic beverages produced by overly aggressive marketing techniques. The Legislature further finds that the exceptions established by this section to the general prohibition against tied interests shall be limited to their express terms so as not to undermine the general prohibition, and intends that this section be construed accordingly.
