Ceefax Turns 30 375
VirtualUK writes "Ceefax, the text information service from the BBC turns 30 today (just 3 days after myself)!! For those not lucky enough to have seen what Ceefax is about, it is text information pages sent in out-of-band data space of TV transmissions in Great Britain. What started off as a subtitling project evolved into a service still used by over 20 million viewers a week even in the face of the Internet revolution. It just goes to show that for a lot of people, the best source of sport results, last minute holiday bargains and horoscopes is still just a click away on their TV remote."
Information non-overload (Score:5, Interesting)
One of the reasons Ceefax/Oracle was so popular was that it gave "just the facts, ma'am". It had to display on a 40x23 (ish) screen to work on the TV's of the time, and most pages used ZX81-style graphics (huge "pixels"
Curiously, this reduced content actually worked in its' favour - about all that could be put on a single page was the raw information, without political or other bias; there just wasn't the space for opinion. Even when they used linked pages (page displays, waits 30 secs, new page displays, repeat and loop) the real-estate was severely limited since each page had to stand alone.
I clearly remember preferring the minimalist information from Ceefax over the long-form in a newspaper. If I wanted more about a story, I could listen to the news or buy a paper, but to get an overview it was ideal. A good example of 'less is more'. It helps that the Beeb has good journalists who can succinctly tell a story, of course...
