Information Before the Internet: Teletext, Ceefax, and Oracle

Before Google, Wikipedia, and even dial-up, there was television teletext—the colourful, blocky, text-filled service that brought news, weather, sports, and more straight into your living room. For Gen X, teletext was often the first place we went for quick facts, scores, or TV listings, long before “googling” was a thing.

The Birth of Teletext

Teletext was born in the 1970s as a way to use the unused lines in a TV broadcast signal to send text and simple graphics. In the UK, the BBC launched Ceefax in 1974, while ORACLE (Optional Reception of Announcements by Coded Line Electronics) started on ITV in 1978. Both services essentially turned your television into an information portal.

The concept was simple: your TV could decode the signals and display pages of information on screen. You navigated through numbered pages using your remote control, waiting for the pages to load one line at a time. It wasn’t instant like today, but it felt revolutionary at the time.

What We Could Find

Teletext covered almost everything. Ceefax and ORACLE offered:

News headlines: A concise snapshot of the day’s events.

Weather forecasts: Local and national predictions, sometimes even international.

Sporting results: Football scores, cricket tables, and racing results.

TV listings: Detailed schedules for the week ahead.

Travel and stock information: Flight times, stock prices, and public transport updates.

Quizzes, horoscopes, and jokes: Because fun mattered too.

The service even included rudimentary graphics, like colourful weather maps and simple animations, which made the pages feel alive.

How It Worked

Technically, teletext used vertical blanking interval (VBI) lines—parts of the TV signal that weren’t used to display the picture. Text and graphics were encoded in these lines, sent alongside the normal broadcast. TVs with teletext decoders could read this information and display it as readable pages.

Users would enter the page number they wanted to see, and the system would cycle through the pages until it reached the one requested. It was slow by today’s standards—sometimes several seconds per page—but it worked, and it was addictive.

Ceefax vs ORACLE

Ceefax (BBC): Focused on news, education, and public service content. It was seen as the authoritative source for reliable information.

ORACLE (ITV): Had a slightly more commercial feel, often featuring entertainment, TV listings, and competitions.

Together, they defined an era in which information was just a button press away, long before the internet became part of everyday life.

Legacy

Teletext may seem quaint now, but it was a huge step in information accessibility. It trained a generation to look for instant answers, and it paved the way for online services in the 1990s. Without Ceefax and ORACLE, the first online news services might have felt a lot less familiar.

For many Gen Xers, flicking through those blocky pages was more than information—it was a daily ritual, a connection to the wider world from the comfort of your living room.

Even in the digital age, teletext remains an icon of pre-internet ingenuity.
