(B) An advertisement supporting or opposing a ballot measure. (C) A radio or television advertisement.

(c) Notwithstanding subdivisions (a) and (b), if an advertisement is a printed letter, internet website, or email message, the text described in subdivisions (a) and (b) may include the words “Paid for by” instead of “Ad paid for by.” (d) Notwithstanding subdivisions (a) and (b), if an advertisement is a text message, the text described in subdivisions (a) and (b) may include the words “Paid for by” or “With,” instead of “Ad paid for by.” (e) Notwithstanding subdivision (a), if an advertisement is a video advertisement that is disseminated over the internet, is a print advertisement that is larger than those designed to be individually distributed subject to subdivision (b) of Section 84504.2, is an electronic media advertisement subject to subdivision (b) of Section 84504.3, or is a text message advertisement subject to Section 84504.7, then the text for the name of the committee may be shortened by either of the following: (1) Displaying only enough of the first part of the committee name to uniquely identify the committee. If the committee is a sponsored committee, then the name displayed must include the portion of the committee name that identifies the sponsor or sponsors, unless all of the sponsors are disclosed on the ad as top contributors as required by Section 84503. For example, if ACME Corporation is not listed as a top contributor, then a committee named “Yes on 99, Californians for a Better Tomorrow, a coalition of X, Y, and Z. Sponsored by ACME Corporation” may be disclosed as only “Yes on 99, Californians for a Better Tomorrow. Sponsored by ACME Corporation.” (2) If the advertisement is paid for by a committee that has top contributors and is subject to Section 84503, then the committee name may be replaced by displaying the words “Committee ID” followed by the committee’s identification number.
