Definition
Material distributed or displayed for the purpose of promoting a product, service, business, or cause to a general or targeted audience. The phrase appears most prominently in statutory contexts where specific legal obligations — such as disclosure requirements, labeling mandates, or regulatory restrictions — apply to "advertising matter," making the scope of the phrase a question of legal interpretation rather than common sense.
The term has no single universal legal definition. Its meaning is determined statute by statute, and courts have repeatedly been called upon to decide whether a particular item — a label, a handbill, a wrapper, a price tag — falls within the phrase as used in a given law.

Common Language
Modern common usage (Wiktionary): Materials used to advertise something; promotional content in any medium.
Historical common usage (Webster's 1913): Not separately defined; "advertisement" is defined as a notice to the public, or a paid notice in a newspaper or other medium calling attention to goods, services, or events.
The gap between common and legal meaning is real and consequential. In ordinary usage, "advertising matter" is understood broadly — anything promotional counts. In statutory interpretation, courts have drawn sharper lines. Material that merely identifies or describes a product (such as a product label) may not qualify as "advertising matter" within a specific statute's meaning, even though such material unquestionably promotes the product in a colloquial sense. Researchers should resist importing the common meaning into statutory analysis.

Common Confusion
ADVERTISING MATTER vs. LABELING: These are frequently conflated, and courts have specifically distinguished them. A label affixed to a product provides identification and regulatory information; it is not necessarily "advertising matter" as that phrase is used in statutes imposing disclosure requirements on promotional communications. The leading illustration is the line of cases holding that product labels do not constitute "advertising matter" for purposes of corporate disclosure statutes — a conclusion that surprises readers who assume the common meaning controls. In federal regulatory law, particularly under the FDCA, "labeling" and "advertising" are treated as distinct categories subject to different regulatory regimes administered by different agencies.

Why It Matters in Research
The phrase "advertising matter" is a statutory term of art, and its meaning shifts depending on which statute governs. Researchers working in the Law Mind corpus need to hold three distinct research threads simultaneously:
First, the historical definitional question. Early cases like the one noted in Bouvier's — resolving whether product labels count as "advertising matter" under a corporate disclosure statute — establish that courts will not automatically apply the broadest reading of the phrase. This interpretive posture carries forward into modern law. Finding how a court defined the phrase in your jurisdiction and statutory context is a threshold research task, not an afterthought.
Second, the regulatory divergence question. In modern federal law, advertising and labeling are formally separated. The FDA regulates labeling of drugs and devices under the FDCA, while the FTC exercises primary jurisdiction over advertising of the same products. The boundary between these regimes is contested and has practical consequences for what disclosures are required, which agency can bring enforcement action, and what First Amendment defenses are available. Researchers moving between health law and intellectual property sources in the corpus will encounter this split repeatedly.
Third, the unfair competition and false advertising question. Under 15 USC 1125(a) and related state law, "advertising" or "commercial advertising and promotion" is an element that plaintiffs must establish. Courts have developed a multi-factor framework to determine whether a defendant's communications constitute "commercial advertising or promotion" — a standard that again diverges from the common understanding of what advertising is.
Historical sources, including Bouvier's, are useful for locating the early definitional disputes but will not help with the modern regulatory framework, which developed almost entirely after Bouvier's last major revision.

Historical Dictionary Support
Bouvier's Law Dictionary addresses the term only incidentally, noting a specific judicial holding that product labels are not "advertising matter" within a statute requiring corporations to print the word "incorporated" on all advertising matter they use. The case cited (96 S.W. 476) illustrates the core interpretive tension: a label performs a promotional function but is not advertising in the statutory sense. Bouvier's offers no broader synthesis or definition, which reflects the fact that "advertising matter" as a general legal category was not highly developed in the period the dictionary covers. The entry is useful primarily as a data point confirming that courts were already restricting the phrase's scope in the early twentieth century.
No other major historical legal dictionaries in the Law Mind shelf develop this term independently. Researchers should not expect historical dictionary support to resolve modern questions about the phrase's meaning in FTC, FDA, or Lanham Act contexts.

Jurisdictional Note
State corporate disclosure statutes using the phrase "advertising matter" vary in how they define or apply the term, and state courts have not uniformly followed the restrictive reading reflected in early cases. Federal regulatory law (FDA/FTC jurisdiction split) applies nationally but creates its own internal complexity. Researchers working on state-law unfair competition or consumer protection claims should verify how the relevant state courts have interpreted the phrase independently of federal precedent.

Encyclopedia Cross-Reference
Unfair Competition and False Advertising — 15 USC 1125(a) (Law Mind Intellectual Property Encyclopedia): Core reference for the "commercial advertising or promotion" element under the Lanham Act and the doctrinal framework distinguishing actionable advertising from other commercial speech.
Drug and Device Advertising — FDCA Restrictions, DTC Marketing, and First Amendment Issues (Law Mind Health Law & Bioethics Encyclopedia): Essential for the FDA/FTC jurisdictional divide and the regulatory definition of advertising versus labeling in the pharmaceutical and device context.
