The net neutrality definition is the principle that ISPs should not discriminate in the transmission of Internet traffic. In the United States, whether that principle is enforceable depends on how the FCC classifies broadband, and the classification has changed repeatedly.
Readers who want the wider field can start with what is technology policy, which places broadband rules among other questions about governing technology.
What net neutrality means
Net neutrality is the idea that an internet service provider (ISP) should carry traffic without picking winners. Legal scholar Tim Wu coined the term “network neutrality” in 2003, according to Cornell’s Legal Information Institute. The same source describes the core principle as non-discrimination by ISPs in how Internet traffic is transmitted.
In practice, the debate centres on three behaviours:
- Blocking: an ISP denies access to lawful content, applications, or services.
- Throttling: an ISP deliberately slows traffic to particular content, applications, or services.
- Paid prioritization: an ISP gives preferential treatment to particular traffic, including when content providers pay for it.
These are the three practices that the FCC’s 2015 rules prohibited and that the 2024 order tried to prohibit again. Net neutrality is therefore a rule about how access networks behave. It does not regulate what websites or apps themselves do.
How the rules work: classification decides enforcement
Net neutrality rules in the U.S. stand or fall on a legal label. The FCC is the primary federal agency regulating broadband Internet access, and the Communications Act gives it different powers depending on the category it assigns to broadband. The sequence below shows how that label controls the outcome.
- The FCC picks a classification. Under Title I, broadband is treated as an information service. Unlike Title I, Title II subjects telecommunications services to common carrier regulation, as Cornell’s summary explains.
- The FCC writes rules that fit that label. Title II classification supported the bright-line bans on blocking, throttling, and paid prioritization. A Title I classification returns broadband to a lighter regime.
- Courts test the choice. Challenges to each order have turned on whether the FCC read the statute correctly and how far its authority reaches, including over state and local regulation.
- The result changes what a user can rely on. When courts uphold a classification, the rules are enforceable. When they reject it, the protections go with it.
This is why the same debate keeps returning. Congress has not settled the classification question, so each FCC majority can choose a different answer. Every answer then has to survive judicial review.
Timeline of FCC rulings and court decisions
The history reads best as a cycle of FCC action followed by court review. The table lists each step in order, using the citations given by Cornell’s Legal Information Institute.
| Year | Action | Effect on net neutrality |
|---|---|---|
| 2005 | FCC Internet Policy Statement outlines four principles for an open and interconnected Internet | Sets policy goals, not bright-line bans |
| June 2005 | Supreme Court (Brand X) upholds the FCC’s classification of cable-modem service under Chevron | Confirms the FCC’s room to choose a classification |
| 2010 | FCC Open Internet Order establishes rules on blocking and unreasonable discrimination, stronger for fixed broadband | First formal rules |
| 2014 | D.C. Circuit in Verizon (740 F.3d 623) vacates the no-blocking and anti-discrimination rules | Rules fall; the classification question stays open |
| 2015 | FCC reclassifies broadband as a Title II telecommunications service and adopts three bright-line rules against blocking, throttling, and paid prioritization | Strongest federal protections to date |
| 2016 | D.C. Circuit in USTA v. FCC (825 F.3d 674) upholds the Title II reclassification | 2015 rules survive review |
| 2017 | Restoring Internet Freedom Order reverses the 2015 classification, returns broadband to Title I, and repeals the 2015 rules | Federal bans removed |
| 2019 | D.C. Circuit in Mozilla v. FCC (940 F.3d 1) largely upholds the repeal but vacates the broad preemption of state and local regulation | Repeal stands; states keep more room |
| 2024 | Safeguarding and Securing the Open Internet Order restores Title II and reinstates the three prohibitions | Federal rules return |
| 2024 | Supreme Court in Loper Bright (603 U.S. 369) ends Chevron deference | Weakens the footing that Brand X relied on |
| 2025 | Sixth Circuit in Ohio Telecom (124 F.4th 993) holds broadband is an information service and sets aside the 2024 order | Title II approach rejected for now |

What the early years established
Between 2005 and 2014, the FCC moved from stating principles to writing rules. It acted first through the 2005 policy statement and then through the 2010 Open Internet Order. The 2014 Verizon decision showed the weakness of that approach. The D.C. Circuit vacated the no-blocking and anti-discrimination rules, which pushed the FCC toward the stronger legal footing of Title II.
The 2015 rules and their repeal
The 2015 reclassification was designed to prevent ISP discrimination against content and service providers, as NYU Law’s explainer describes it. The FCC then voted to repeal those rules in December 2017. A Syracuse Law Review piece dates the vote to December 14 and reports it as 3-2. The repeal drew a response from Congress. According to NYU Law, Sen. Ed Markey, Rep. Anna Eshoo and 103 colleagues filed an amicus brief on August 28, 2018, in the court challenge.
The 2024 order and the Sixth Circuit
The 2024 order reinstated Title II and the three prohibitions. It did not last. In 2025 the Sixth Circuit held that broadband Internet access service is an information service and set aside the 2024 order. The Loper Bright decision matters here because Brand X had upheld the FCC’s classification under Chevron, and Chevron deference ended in 2024. The FCC can no longer count on courts accepting its preferred reading of the statute.
How it affects users
For a household, net neutrality shows up as the difference between a network that delivers lawful services on equal terms and one that can favour some of them. Each of the three practices affects users differently.
- Throttling shows up as one service, such as video or a particular app, running slowly while the rest of the connection seems fine. It is the deliberate slowing of traffic to particular content, applications, or services.
- Blocking removes access to lawful content or services altogether, which is a more visible failure than slowdown.
- Paid prioritization is mostly invisible to subscribers. Content providers that pay an ISP can receive preferential treatment, and the effect is felt by services that cannot or will not pay.
Since the 2025 ruling set aside the 2024 order, the federal rules against these practices are not in place. What a subscriber can count on depends on the ISP’s own policies, on competition in the local market, and on any state or local regulation. The 2019 Mozilla decision vacated the FCC’s broad preemption of state and local regulation, so that regulation is a live question. If a service seems to be singled out for slowdown, log the service, the time, and the results of repeated tests. A pattern is far more useful to a regulator or reporter than a single bad evening.
Related policy questions
Net neutrality limits the behaviour of access providers, so it sits apart from the broader question of platform power. For how regulators approach large technology companies, see Big Tech Regulation In 2026: Balancing Innovation, Power, And Privacy – Technopolicy. Blocking by an ISP is also distinct from restrictions on speech imposed more broadly, which is covered in What Is Internet Censorship?

Frequently asked questions
Is the 2024 net neutrality order still in effect?
No. According to Cornell’s Legal Information Institute, the Sixth Circuit set aside the 2024 order in 2025 after holding that broadband is an information service.
Does net neutrality apply to streaming services and websites?
The principle is aimed at ISPs, not at websites or apps. Content providers appear in the debate mainly as parties that might pay an ISP for preferential treatment.
Can states set their own net neutrality rules?
The 2019 Mozilla v. FCC decision upheld most of the 2017 repeal but vacated the FCC’s broad preemption of state and local regulation, which left room for such rules.
Why does the end of Chevron deference matter?
Brand X upheld the FCC’s cable-modem classification under Chevron. Loper Bright ended that deference in 2024, and the Sixth Circuit’s 2025 ruling then rejected the Title II approach for broadband.
