Why Do We Say ‘In the West End’ but ‘On Broadway’?

There is a tiny grammatical difference between a musical is playing in the West End but on Broadway, and apparently I have been getting it wrong for most of my life. I had always said that a production was playing “on the West End”. Actors perform on stage; shows are on Broadway; it seemed perfectly logical. However, after a particularly fruitful comment from one of my social media followers, I discovered that the correct grammar is “in the West End”. So why do two of the world's biggest theatre districts use different prepositions, and does getting it wrong really matter?

It's all geography... The West End is an area of London, rather than the name of a road. When something exists within a larger geographical space, it's in London, in Soho, in Covent Garden, in the West End. Theatre usage follows exactly that convention. After all, you wouldn't say you'd gone for dinner “on Soho”.

Broadway is different because Broadway is actually a street. So it's like being on Oxford Street, on Shaftesbury Avenue and on Broadway. The ridiculous complication is that a Broadway theatre does not actually need to be on Broadway; most Broadway theatres sit on the surrounding cross streets. The phrase has therefore outgrown its literal geography while keeping the grammar it inherited. Theatre loves tradition, apparently right down to its prepositions.

That also explains why “on the West End” sounds so plausible. Productions transfer between London and New York, actors work on both sides of the Atlantic, and audiences routinely discuss the West End and Broadway in the same sentence. Once you have learned "on Broadway", extending the same pattern to "on the West End" is hardly evidence that you have suffered some catastrophic educational failure.

So, if somebody says, “I saw Hamilton on the West End,” everybody understands them. Nobody imagines the cast physically balanced on top of London's western extremity. Deciding somebody's theatrical opinion is worthless because they chose the wrong word is gatekeeping dressed as grammar. If you have spent years saying “on the West End”, it's fine; there is really no need to make a dramatic production out of it... Because trust me, it wouldn't sell very well in the West End.
