I don't really know how the ad industry works, but from anecdotal observation, it seems to me that advertisements usually won't be taken down until someone else buys that ad space. I'm guessing this is why you sometimes see very outdated ads, especially in less trafficked area. In some subway stations in the boroughs, or the MetroNorth stops in the suburbs, it's not uncommon to see advertisements for movies that came out years ago, or Broadway shows that closed years ago. Near where I used to live, there is still (last time I checked) an ad for Secret Life of Pets - the FIRST one, not even the sequel!
I would imagine that, with Times Square being more empty these days (due to lack of tourism and theatre), advertisers are reluctant to buy expensive ad space in that area. So they just leave up the old ads.
