Definition
Public notices or communications directed at an audience to promote, announce, or call attention to goods, services, events, or legal proceedings. In law, the term encompasses a broader range of communications than everyday usage suggests. Legal meaning extends to:
1. Commercial advertising: Representations made to consumers to promote the sale of goods or services, regulated under federal and state unfair competition, consumer protection, and sector-specific statutes.
2. Legal notices: Formal public notices required by law — such as notices of foreclosure, probate, sheriff's sale, or public hearing — that must be published in prescribed form, often in a newspaper of general circulation or other designated medium.
3. Regulatory filings and disclosures: In securities, pharmaceutical, financial, and broadcasting law, "advertisement" carries specialized statutory definitions that may include prospectuses, labels, promotional materials, and solicitations that would not ordinarily be called advertisements in common speech.

Common Language
Modern common usage (Wiktionary): Plural of advertisement — commercial notices or announcements, typically paid, promoting goods, services, or events.
Historical common usage (Webster's 1913): A notice given; an announcement; especially, a paid notice in a newspaper or other publication calling public attention to something.
The legal meaning is not confined to paid notices in newspapers or other commercial media. Courts have recognized that an "advertisement" in its legal sense may include oral announcements, posted notices, circulars, labels, and other communications to the public regardless of whether they are paid for or commercially oriented. The gap matters most in the context of required legal notices, where the question of what medium or format satisfies the legal requirement of "advertising" can determine whether a proceeding is valid.

Why It Matters in Research
The most persistent trap in historical sources is the implicit equation of "advertisement" with newspaper publication. Black's Law Dictionary preserves a useful corrective: the word, in legal usage, is not confined to notices printed in newspapers (citing 5 Pick. 42). Researchers working with older statutes, probate records, and court orders should not assume that a legal requirement to "advertise" was satisfied only by newspaper publication — nor that the absence of a newspaper notice means the legal requirement was unmet if another form of public notice was used.
Jurisdictional and statutory variation is significant. Modern federal regulatory frameworks — particularly under the Lanham Act (15 U.S.C. § 1125(a)) for false advertising, the Federal Food, Drug, and Cosmetic Act for drug and device promotion, and SEC rules for securities — each define "advertisement" differently for their purposes. A communication that qualifies as an advertisement under one regulatory scheme may not under another. Researchers moving across practice areas must check the operative statutory definition rather than relying on a general legal definition.
In consumer protection and Lanham Act false advertising litigation, "advertisement" and "commercial speech" function as threshold concepts. Whether a communication constitutes an "advertisement" or "advertising" within the meaning of 15 U.S.C. § 1125(a) has been the subject of substantial litigation, with courts applying multi-factor tests to distinguish actionable advertising from individual statements or internal communications. Researchers should connect this term to the corpus material on unfair competition before assuming a communication qualifies.
For health law researchers, the FDCA's regulation of drug and device advertising extends to promotional labeling, direct-to-consumer marketing, and off-label promotion — all of which may be treated as "advertising" for regulatory purposes even when the sponsor would not characterize them that way. First Amendment issues arise at this intersection and are addressed separately in the encyclopedia entry.

Historical Dictionary Support
Black's Law Dictionary's entry is brief but pointed: it flags that the legal meaning of "advertisement" is not confined to notices printed in newspapers, citing an early Massachusetts case (5 Pick. 42). This reflects a consistent thread in legal usage — courts and legislatures have long understood the term more broadly than its popular sense, covering any form of public notice directed to a general or specified audience.
Historical legal dictionaries generally treat the term in two registers: the procedural (required legal notices ancillary to court proceedings, sales, or government actions) and the commercial (promotional communications in trade). Older sources weight the procedural meaning more heavily, reflecting the historical importance of publication requirements in common law practice. Modern sources, including current editions of Black's, have expanded coverage of the commercial and regulatory dimensions substantially, tracking the growth of advertising law as a distinct field.
What historical sources largely miss is the regulatory fragmentation of the term across modern federal agencies. The FTC, FDA, SEC, FCC, and CFPB each operate with functional definitions of "advertisement" tailored to their enabling statutes — a complexity that no single-volume legal dictionary can fully capture and that requires researchers to consult primary regulatory sources.

Jurisdictional Note
State statutes governing required legal notices — including publication requirements for probate, foreclosure, and public procurement — vary considerably in what media and formats satisfy the "advertisement" requirement. Several states have updated publication statutes to recognize online publication alongside traditional print. Researchers relying on historical state-law sources should verify whether the applicable jurisdiction's definition has changed before concluding that a historical notice did or did not satisfy the legal requirement.
