It might seem odd to be contemplating the future of Test cricket in the middle of a sold-out Ashes summer.
But the undimmed appeal of five-day contests between England and Australia only highlights the wider problem in other countries.
In India, South Africa, Sri Lanka, New Zealand – and even to a certain extent Australia – crowds for Test matches are falling. Set against the growing popularity of Twenty20 cricket (particularly in India and Australia) there are concerns at the highest levels of the game that its most traditional format could die out.
For The Editors, a BBC programme which sets out to ask challenging questions, I decided to find out whether Test cricket, the longest and oldest form of the game, has a future.
If that sounds alarmist then don’t take my word for it. This is what former England captain Andrew Strauss thinks: “If we are arrogant enough to assume that Test cricket will always be there, we are sowing the seeds of our own downfall.”
But ask most fans and professional players and they will still tell you that Test cricket remains the pinnacle.
So what exactly is the problem?
On the playing side it’s a question of money. The emergence of well-funded T20 competitions like the Indian Premier League and the Big Bash in Australia has shifted the financial balance of power away from Test cricket to the shortest form of the game.
Consider Forbes’ 2012 list of the highest earning cricketers. Six of the top 10 are Indian with MS Dhoni the highest paid player in the world with earnings of $26.5m (£17.3m). The other four players in the top 10 are all Australian.
