A 1990 law capped children's TV adverts and tied it to licences

The short answer

Since 1990, a federal law has required every US television broadcaster to limit advertising during children's programmes and to show it has served children's educational needs before its licence can be renewed. It is a rare example of a content-adjacent obligation attached directly to the right to broadcast.

What the evidence says

The Children's Television Act became law on 18 October 1990. Under the codified advertising-limit provision, Congress directed the Federal Communications Commission to begin a rulemaking within thirty days and finish it within one hundred eighty, and set the eventual standard itself: no more than ten and a half minutes of commercial matter per hour on weekends, and no more than twelve minutes per hour on weekdays, during programming aimed at children, a limit that explicitly reaches cable operators as well as broadcasters. Congress said the safeguards were needed to protect children "from overcommercialization on television" while recognising that advertiser support helps fund the programming in the first place. A companion provision, the licence-renewal review requirement, obliges the FCC to check, before renewing any station's licence, whether it complied with the advertising standard and served children's educational and informational needs through its overall programming, a requirement extended to noncommercial as well as commercial stations.

For context

The statute sets a clock and a ceiling; it does not itself define how many hours of educational programming count as "serving" children's needs, a judgment left to the FCC's own rulemaking record, separate from the statute. A minutes-per-hour advertising cap is also narrower than it might sound: it limits commercial time, not commercial content, tone or the persuasive techniques used within that time. And a licence-renewal review is a periodic check, not a continuous one, so a station's compliance in any given week is not directly observable from the statute alone.

A practical next step

Because this law regulates broadcast and cable licensees rather than streaming platforms, it can be worth checking, for any specific service a family uses, whether it is covered by this framework at all before assuming the same advertising limits apply.

• Is the programme a child is watching delivered by a broadcaster or cable licensee this law covers?
• Is a show's "educational" label backed by a licence-renewal filing, or only by marketing copy?
• Where advertising limits do not apply, what other cue tells a family how much commercial content a child is seeing?

Three decades later, the Children's Television Act remains a useful model of what a content obligation can look like in practice: not a ban, but a measured limit and a periodic, licence-linked check.
