Reno v. ACLU

In 1996, as the commercial internet was just beginning to reach mass audiences, Congress passed the Communications Decency Act as part of a larger telecommunications reform bill. The CDA included two provisions — the 'indecency' and 'patently offensive' clauses — that made it a federal crime to transmit material deemed indecent or patently offensive to persons under 18 over the internet. The law's sponsors argued it was necessary to protect children from the flood of explicit material available online, analogizing the internet to broadcast television, which had long been subject to reduced First Amendment protection because of its pervasiveness and accessibility to children.

The ACLU, along with a coalition of libraries, news organizations, and online service providers, filed suit the same day the CDA was signed, arguing that the provisions swept far beyond child pornography to cover vast amounts of constitutionally protected speech for adults. A three-judge district court agreed and struck down the provisions, finding that the internet was more like print than broadcast and deserved the highest constitutional protection. The government appealed directly to the Supreme Court.

Justice John Paul Stevens wrote the unanimous opinion affirming the district court. The central holding was that the internet is not broadcast media and does not share the features — spectrum scarcity, pervasiveness, intrusiveness into the home — that justified reduced First Amendment protection for radio and television under FCC v. Pacifica Foundation. Instead, the internet more closely resembles a printing press or public street corner: a medium in which any speaker can reach a global audience, deserving of the highest level of First Amendment scrutiny.

Applying strict scrutiny, the Court found the CDA's indecency provisions unconstitutional because they were not narrowly tailored to serve the government's interest in protecting minors. Less restrictive alternatives — parental filtering software, for example — were available and adequate. Stevens's opinion famously described the internet as 'a vast democratic forum' and 'a unique and wholly new medium of worldwide human communication,' language that became foundational for subsequent internet speech jurisprudence.

Reno v. ACLU is the constitutional foundation of internet free speech law. By rejecting the broadcast analogy and extending full First Amendment protection to online expression, the Court ensured that the legal framework developed for print media — rather than the more permissive framework for regulated broadcast — would govern the emerging internet.

The decision had an immediate practical effect: it prevented Congress from using the CDA's broad indecency standard to impose pervasive content restrictions on online expression. But its significance extends well beyond the specific provisions at issue. Stevens's recognition that the internet enables ordinary citizens — not just licensed broadcasters or major publishers — to reach mass audiences without requiring government permission established the constitutional premise for three decades of online expression.

Reno also interacts with Section 230 of the CDA, which was in the same legislation and survived the First Amendment challenge. Section 230's immunity for platforms hosting user-generated content, combined with Reno's protection of online expression from government regulation, created the dual legal foundation on which the modern internet was built.

Reno has governed internet First Amendment law for nearly three decades, surviving the transformation of the internet from dial-up bulletin boards and text-heavy websites to social media platforms with billions of users, streaming video, algorithmic content curation, and AI-generated content. Its core holding — that internet expression receives the same protection as print, not the lesser protection of broadcast — has been reaffirmed in virtually every major internet speech case since 1997.

Packingham v. North Carolina (2017) cited Reno's framework when striking down a law barring sex offenders from social media, with Justice Kennedy describing social media as the modern equivalent of the public spaces that Reno had said the internet resembled. Moody v. NetChoice (2024) similarly applied Reno's premise that the internet deserves robust First Amendment protection when evaluating state content moderation laws. The decision's framing of the internet as a democratic forum for all citizens, rather than a regulated public utility, has repeatedly prevailed over efforts to import broadcast-style regulation into online speech law.

Reno's framework faces new questions in an era of platform dominance, algorithmic amplification, and AI-generated content that Reno's authors could not have contemplated. Critics argue that when a handful of platforms mediate virtually all public discourse, the premise that anyone can speak freely online is more aspirational than real, and that Reno's framework provides inadequate tools for addressing the concentration of expressive power in private hands.

As Congress and regulators consider laws targeting AI-generated disinformation, youth access to social media, and algorithmic manipulation, Reno remains the starting point for constitutional analysis. Any federal regulation of online speech content must reckon with Reno's holding that the government cannot impose indecency-style content restrictions on the internet without passing strict scrutiny — a standard that, in nearly three decades of application, has proven extremely difficult to satisfy.
