Cricket spent well over a century organised around international matches between national teams, with domestic competition as a feeder system. Franchise leagues in the short format inverted that within about fifteen years.
The consequences run through every part of the sport and they're worth laying out, because they're a fairly clean case study in how a format change reorganises an industry.
Why the format mattered
The shortest format is roughly three hours, fits an evening, has a guaranteed result, and requires no prior knowledge to follow. That makes it a television product in a way that multi-day cricket never could be.
Three hours is also a coherent advertising inventory. Broadcasters can sell it, schedule it, and repeat it nightly across a season, which is what generates the revenue that funds everything else.
The comparison with the longest format is stark: five days, no guaranteed result, and an audience that has to be available across a working week.
The franchise structure
The second innovation, and arguably the more important one.
City-based teams, privately owned, with players allocated through an auction, playing a compressed season. That's the structure of most major team sports leagues and it was new to cricket.
It creates several things international cricket doesn't have. Permanent club identities that fans attach to. A regular annual calendar. Ownership with incentive to invest in the product. And a transfer or auction mechanism that generates its own coverage and drama.
The auction in particular turned out to be an enormous media event in its own right, which nobody predicted.
What it did to player economics
The most consequential change. Players could earn substantially more in a short franchise season than from a year of international contracts, particularly for those outside the wealthiest boards.
That inverted the traditional hierarchy. National selection was the route to income; now the leagues were, and international cricket became partly a route to visibility that increased league value.
The specific effect is on players from boards with limited resources. A player from a smaller cricketing nation can earn multiples of their national contract in franchise cricket, which creates an obvious tension when the two calendars conflict.
Several players have retired from longer formats, or from international cricket entirely, to maximise franchise availability. Each individual decision is entirely rational and collectively they change the sport.
The calendar problem
The unresolved structural issue. There is a fixed number of days in a year and the demands on them have multiplied.
Leagues have proliferated across multiple countries, each wanting a window. International cricket continues across three formats. Players cannot be in two places at once.
The result is scheduling conflict, players choosing between commitments, and boards competing for availability. National teams have fielded weakened sides during major league windows.
Proposals to rationalise the calendar have circulated for years. The obstacle is that reducing anybody's window reduces their revenue, and the parties involved have unequal negotiating power.
The revenue concentration
An effect worth stating plainly. Cricket's revenue is heavily concentrated in a small number of markets, and the franchise model has amplified that.
Broadcast rights for the largest leagues dwarf what smaller boards can generate from any activity. That funds domestic infrastructure, player payments and development in those markets, and doesn't reach others.
Smaller boards have responded by launching their own leagues, with varying success. Those that have found a market have gained a revenue source; those that haven't have added to calendar congestion without solving anything.
What happened to the long format
The question that generates most argument.
The long format remains prestigious and is loss-making in most markets. It requires five days of production for uncertain audience, and outside a handful of series between major nations, attendances and viewership are modest.
Boards fund it from revenue generated elsewhere — increasingly from the leagues. Which is a somewhat awkward position: the format regarded as the sport's highest expression is subsidised by the one regarded as its most commercial.
Various proposals exist to make the long format more viable — a formal championship structure, day-night matches, reduced duration. Each has been tried in some form with mixed results.
My own read is that it survives as a prestige product funded by the commercial format, similar to arrangements in other sports where a traditional form is maintained for reasons other than profitability. That's a sustainable position as long as the funding continues and the people making the decisions continue to value it.
The transferable lesson
For any sport considering a format change: the money follows the format that fits a broadcast window and produces a guaranteed result, and once it does, the players follow the money, and the traditional structure becomes dependent on the new one.
Whether that's a loss depends on what you valued about the traditional structure. What's not in question is that the causation runs in that order, and that it happens faster than governing bodies expect.
What it did to player development
A consequence still working through. The skills rewarded in the short format differ from those rewarded in longer ones, and young players optimise for where the money is.
Batting techniques built for constant scoring pressure differ from those built for occupying the crease across sessions. Bowling that prioritises variation and containment differs from bowling designed to take wickets over long spells.
Coaches at youth level report the shift clearly, and it is entirely rational — a teenager can see where a career is available.
Whether this degrades the longer format's quality over time, or simply produces differently skilled players who adapt, is genuinely contested. What is not contested is that the incentive gradient now points one way, and that it did not use to.
