From BT to AI
Nearly fifty years of debates in Parliament, read one by one: how much time MPs and peers give to science and technology, what they argue about, and which arguments keep coming back.
Every Parliament has its machine
The subjects change, but the pattern holds. A new technology arrives, Parliament argues about who owns it, who it harms and who can see what it collects, and then it passes a law.
In the 1980s the argument was about telephones and computers in government hands. By the 2000s it was masts, broadband and television. Since the 2019 election it has been platforms, data and AI.
What each Parliament talked about most
The most-debated subjects in science, technology and digital, from one general election to the next, with one landmark debate from each.

New words, then a flood
The first debate with “internet” in its title was in 1994. “Cyber” arrived in 2005, “social media” in 2013 and “AI” in 2017.
Once a word arrives, it can spread fast. AI first appeared in a debate title in 2017. Since the 2024 election it has been in 72. That is about 31 a year. Cyber, first in a title in 2005, has never passed 16 a year.
“Computer” went the other way. It was in 107 debate titles in the four Parliaments to 1997, and 59 since. Once computers were in everything, nobody needed to name them.
The first internet debate, in December 1994, was about the government’s plans for “information superhighways”: Internet, 15 December 1994.
Debates with each word in the title
Policy debates in both Houses a year, Parliament by Parliament from 1979–83, so short and long Parliaments compare. Every chart uses the same scale. The current Parliament runs to October 2026. Titles are Hansard’s own headings.

Arguments that never end
Some questions come back to Parliament every decade or so: what the state can know about you, whether you should carry an ID card, and how to keep children safe from new screens.
Parliament has passed a data protection law four times: in 1984, 1998, 2018 and 2025. The powers of the police and security services to read communications have been legislated for four times since 2000. Every national ID scheme put to Parliament since 1988 has been dropped or reversed. Rules on what children see on screens run from video nasties in 1984 to the ban on social media for under-16s announced in 2026.
Four arguments, 1979 to 2026
Debates each year that name the subject in their title or main issue, in any topic. Taller bars mean more debates; the scale is compressed so quiet years still show.
Data protection
432 debates in 44 different years. Four laws: 1984, 1998, 2018, and the Data (Use and Access) Act in 2025.
Surveillance powers
333 debates in 33 different years. The Regulation of Investigatory Powers Act 2000, an emergency data retention law in 2014, the Investigatory Powers Act 2016 and its update in 2024.
National ID
204 debates in 32 different years. Private members' bills in 1988 and 1989; football ID cards, law in 1989 and shelved in 1990; the ID Cards Act 2006, scrapped in 2010; digital ID, announced in 2025 and cancelled in 2026.
Children and screens
296 debates in 31 different years. Video nasties in 1984, age checks on pornography in 2017 (dropped in 2019), the Online Safety Act 2023, and a ban on social media for under-16s announced in 2026.
The Lords do more than their share
Since the 2019 election, 39% of debates on science and technology were in the House of Lords. For all policy debates the figure is 34%.
Over the whole record the two are close: 35% against 32%. The gap has opened recently. Many of the long arguments over the Online Safety Bill, data law and AI were in the Lords, where bills get line-by-line scrutiny and peers include former scientists, regulators and technology executives.
If you run a technology start-up
- Expect the rules to come back. Data, surveillance, ID and children online have each been legislated for again and again. A settled law in your sector is a pause, not an end.
- Watch for the new word. When a technology starts appearing in debate titles, rules tend to follow within a few years. AI first appeared in a title in 2017; since the 2024 election it has been in 72.
- Follow the Lords. Since 2019, 39% of technology debates have been in the Lords, more than its share of debates overall. Watch Lords amendments to technology bills closely.
- Big bills move the dial. Each spike in the chart is one or two large bills. When one is announced in the King’s Speech, expect a year or more of debate in which the detail can change.

How we did this
Method and caveats
Data. Every debate in the House of Commons and House of Lords from January 1979 to October 2026, from the Hansard API: 356,419 items, each one a heading in Hansard with its own page. Written statements and written questions are not included.
Tagging. An AI model (Claude Haiku) read each debate’s title and opening text and gave it one main topic from a list of 20, up to two more topics, a stage (from an idea being raised to a law being revisited) and a one-line summary. It was told to judge from the text alone, without hindsight. We checked a sample of 300 debates from 1997 against a larger model (Claude Opus): the two agreed on the topic 90% of the time.
The share. Debates mainly or partly on science, technology and digital, as a share of all debates with policy content. Formalities, such as prayers, the order of business and empty headings, are left out of both sides: 117,845 items.
Words in titles. Counted on Hansard’s own debate titles, not our summaries, so they show what Parliament called a debate at the time. “AI” counts the capital letters AI or the words “artificial intelligence”.
The four arguments. Debates whose title or main issue names the subject, in any topic: a debate on data retention may be tagged as crime rather than technology. The landmark debates and the subjects in each period were chosen by us from the most-debated subjects in that period.
Limits. Before about 2000, Hansard often gives each clause or amendment of a bill its own heading, so a big bill counts many times. That is part of why 1983 and 1998 stand out. Merging the headings from the same day and issue barely changes the trend: the share goes from 1.6% in the 1979–83 Parliament to 5.9% in the current one. Debates from January to April 1979, before that year’s election, count in the yearly figures but not in any Parliament. About one debate in five from the early 1980s has no text online, only a title, and was tagged on the title alone. 2026 runs to October 2026, and the most recent weeks may still be filling in.
