40 years ago today (April 3rd 1973) Martin Cooper made the first mobile call on the nine-inch (and 28-ounce) Motorola DynaTAC, which had a talk-time of 35 minutes and took 10 hours to recharge. It is thought he was dialing up a rival at AT&T to see if his call ‘sounded good’ on the other end. But little did he know that in four decades time the worldwide telecoms industry would be generating annual revenues of £800bn. Nor did he know how much the mobile phone would change over time, in design, usage and cost.
The average mobile is now used to take photos, play music and games, send emails, download maps, watch video clips, all as well as talking and texting. And it isn’t likely to stop there either.
Take a look at the timeline here.
