I have a laptop, a tablet and a smartphone, but I would still rather have a printed programme.....
It's probably a very minor consideration (to the clubs, anyway) but there are people who collect programmes. I have the Le Mans programme for every year I've been 1986-2019, plus 2021 and a number from before my Le Mans trips started. I'd be very disappointed indeed if the ACO stopped producing a programme - even though I have many that I've never opened (or even unwrapped).
I have a collection of Le Mans
Information Presse - Media Guides which I've managed to collect, many with the aid of a well known commentator who is a personal friend. I have all of them between 1986 and 2010 and was gutted when the guides went digital in 2011......
Sometimes having something physical is a lot better than something virtual....
