Titan has owned and operated all of the city's remaining phonebooths for near 20 years. And I believe the MTA bus stop and subway advertising too. This is something they've already been doing.
Control Group developed those info kiosks you may have seen on subway platforms. They're good people that have got some cool tech. They even post in Who's Hiring here frequently (Hi, Ben!).
If this is something that the city wants, I don't see that there's another way that they would get it. The real problem that I have with LinkNYC though, especially in midtown where I live, is that all the terminals have become 24/7 campgrounds for the city's homeless. They charge their phones and browse the web there. There is no way that I would use one of these things now.
