Here in slovenia, the "real world" ad space (public ad displays, posters, jumbo posters,...), which was once full of ads for random commercial stuff (supermarkets, cars, fashion brands...) is now getting filled with ads for blood donations (nationalized healthcare, so not a private clinic), theatre and drama stuff (again, state financed) and even some leftover anti-firecracker 'ads' still left on since the time before the new year. There are still a lot of purely commercial ads, but the ratio is visibly shifting, as if companies are running out of marketing budgets, or don't want to advertise during the "depressive" months (people spent money for presents in december and are not spending so much now).
Could be anecdotal and just something happening locally though.
