You can watch the original Law & Order both via streaming services and live TV, but availability varies a bit by region and by season as of 2025–2026.

Where to watch Law & Order (quick list)

  • Peacock (US) – Many recent seasons of the original Law & Order and new episodes, usually available the day after they air on NBC.
  • Hulu (US) – Large on‑demand catalog for the original series, including many earlier seasons.
  • NBC (live TV) – New seasons/episodes broadcast Thursday nights on NBC; next‑day streaming typically on Peacock.
  • Live TV / cable bundles – Reruns frequently on USA Network, Ion, WE tv, Sundance, and others, and via providers like DIRECTV, YouTube TV, Philo, and similar live‑TV streamers.
  • Digital purchase – Buy individual seasons/episodes on Amazon/Prime Video, Apple TV, and Fandango/Vudu if you prefer to own them.
  • Roku aggregation – Roku’s “Where to Watch” pages surface options like Hulu, Prime Video, and Fandango at Home for Law & Order in one place.

Mini‑example: if you want to binge from the very beginning, many viewers start with Hulu’s Season 1–20 library, then switch to Peacock or NBC for the newest seasons.

Streaming vs. live TV

  • Streaming on demand : Hulu and Peacock are the main “all‑you‑can‑watch” hubs; they cover most seasons and make it easy to binge.
  • Live premieres : New episodes debut on NBC, then move to Peacock (and sometimes other live‑TV apps) the next day.
  • Cable reruns : If you like channel‑surfing and marathons, networks like USA Network, Ion, WE tv, and Sundance often run long blocks of episodes.

Spin‑offs (if you meant the franchise)

If by “Law & Order” you meant the whole franchise, the pattern is similar:

  • Law & Order: SVU – All seasons on Peacock and Hulu, with new episodes hitting Peacock the day after NBC.
  • Law & Order: Organized Crime – Recent seasons on Peacock; episodes also show up via NBC and some live‑TV providers.

These spin‑offs usually live in the same apps as the original, which makes “Thursday night L&O” marathons easy to follow.

Platform What you get Notes
Peacock Many seasons of original, SVU, Organized Crime; next‑day new episodes Key home for current NBC runs and recent seasons.
Hulu Large back catalog of original series and SVU seasons Great for long‑term binge from early seasons.
NBC (broadcast) New episodes of the latest seasons Watch live on Thursday nights, then shift to Peacock next day.
Live‑TV streamers / cable Reruns and marathons across USA, Ion, WE tv, etc. Good if you like flipping channels and surprise episodes.
Digital stores (Prime Video, Apple TV, Fandango) Purchase seasons or individual episodes Best if you want permanent access without subscriptions.

TL;DR

If you just want the easiest path right now: use Hulu for big chunks of older Law & Order, then Peacock and NBC for the latest episodes and other franchise spin‑offs.
