A survey of UK consumers has found that the Apple iPhone is considered to be a more significant innovation than landmarks such as space flight and even indoor plumbing.
Over 4000 people took part in the study and the humble wheel rolled away with the top spot, with the world wide web in fourth place, bizarrely ahead of computers - without which you'd have to say it could not actually exist.
The iPhone ranked in eight position, just ahead of the flushable toilet and the combustion engine.
Tesco Mobile surveyed a mixed group of different ages and genders between 18 and 65 years old in an attempt to discover which devices most people believe have had a world-changing impact.
"It's amazing to see how much the iPhone is valued, sitting alongside inventions such as Penicillin in people's perceptions and being declared a more important invention than miracle gadgets of their own time, such as the compass," said Tesco's Lance Batchelor.
The iPhone is considered more important that mobile phones in general, an innovation which just missed out on the top 20, coming in at number 21.
