Here’s something your students may find mildly amusing. This music video from 1992 features several examples of technological changes; can you spot them?

Here’s what you might have noticed:

• Mercury phone booth.
• Switchboard: one of the old-fashioned types where the operator had to physically plug different cables in to the board to connect people with each other over the phone network.
• Instruments: the musicians are playing real ones, not synthesisers.
• Microphone: a big old-fashioned one, not a headset mike (which was first used years before by Kate Bush, apparently).
• Wristwatch: someone is wearing one. These days, young people tend not to because they use their cell phones to find out the time and a whole load of other functions.
