2 senses
1
commercial speech
A structured inquiry used to evaluate government restrictions on commercial speech. The analysis first determines whether the speech concerns lawful activity and is not misleading. If that threshold is met, the government must then show a substantial interest, that the regulation directly advances the interest, and that the restriction is not more extensive than necessary.

Examples2
Streaming Ad Ban Challenged
PharmaCorp runs truthful online video ads for prescription drugs that include risk disclosures. The State Health Authority bars all such streaming ads and allows only print ads in medical journals. PharmaCorp sues, claiming the ban violates the First Amendment. A court applies the four-pronged analysis to decide whether the speech is protected and whether the medium-based restriction satisfies the remaining steps of substantial interest, direct advancement, and reasonable fit.
Sense 2
2
other-act evidence
A four-part test applied to determine the admissibility of other-act evidence under Federal Rule of Evidence 404(b). The court evaluates whether the evidence is offered for a proper purpose other than propensity, whether the prior act is similar and sufficiently close in time, whether the evidence is sufficient for a jury to find the act occurred, and whether the probative value is not substantially outweighed by the danger of unfair prejudice.

Below-Cost Sale Advertising
MetroMart publishes accurate circulars and banner ads announcing time-limited below-cost sales on lawful products. A state statute forbids such ads by large chains to protect smaller stores. MetroMart seeks an injunction. The court uses the four-pronged analysis to determine that the speech qualifies for protection and that the categorical ban fails the tailoring requirement.
Frequently Asked2
What is the first step in the commercial speech four-pronged analysis?+
The court first asks whether the speech concerns lawful activity and is not misleading. Speech that fails this threshold receives no First Amendment protection and may be banned outright.
Supporting sources
How does the four-pronged analysis differ from rational basis review?+
Rational basis review applies to ordinary economic regulation. The four-pronged analysis imposes intermediate scrutiny on restrictions of truthful commercial speech by requiring a substantial interest, direct advancement, and reasonable fit rather than mere rationality.

Frequently Asked1
When is other-act evidence admissible under the four-pronged analysis?+
The evidence must be offered for a non-propensity purpose, concern a sufficiently similar and recent act, be adequate for a jury finding, and have probative value that is not substantially outweighed by unfair prejudice.
