Last week, Mike and I were at a conference celebrating the 20th anniversary of the Supreme Court decision in Reno v. ACLU, a seminal case that declared that the First Amendment applied online. What makes the case so worth a conference celebrating it is not just what it meant as a legal matter – it‘s a significant step forward in First Amendment jurisprudence – but also what it meant as a practical matter. This decision was hugely important in allowing the internet to develop into what it is today, and that evolution may not be something we adequately appreciate. It‘s easy to forget and pretend the internet we know today was always a ubiquitous presence, but that wasn‘t always so, and it wasn‘t so back then. Indeed, it‘s quite striking just how much has changed in just two decades.
