No domestic insurer shall knowingly solicit or advertise its insurance business in a state or jurisdiction in which it is not licensed as an authorized insurer. Provided, however, that this section shall not prohibit a domestic insurer from advertising through publications, radio or television if such advertising is not expressly directed toward the residents or subjects of insurance in a foreign state or other jurisdiction. Nor shall this section apply to trade journals or directories.
