Seeing as we have been talking about trademarks...
Back in June, I wrote on this blog about the number of different terms there are for ATMs. One of the ones I mentioned was 'hole in the wall' - and I've just found out that 'hole in the wall' is a trademark of Barclays Bank. Or rather, 'Hole in the Wall' as Barclays would have it.
Interestingly, 'hole in the wall' is listed in the OED – but as 'informal, British', not as a trademark. I wonder when Barclays trademarked it? The bank only started consistently using the term 'hole in the wall' instead of 'ATM' last year – but then it did install the world's first 'hole in the wall', in Enfield, North London, 40 years ago.
