Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth’s speed around the Sun.

A great white shark is a masterwork of evolutionary engineering. These beautiful predators glide effortlessly through the water, each slow, deliberate sweep of the powerful tail driving a body specialised for stealth, speed and efficiency.

It’s almost too easy to make the case that men’s football in England has become overly commercial. At the start of this season, one Premier League striker cost £125 million. And with an annual TV broadcasting deal worth £1.25 billion, more money is flying around the top level of the sport every year.
But it hasn’t always been this way. So how has the sport become so dominated by commerce?
