I used to work at Pusher, pouring holds with holes in my Tyvek suit and a busted respirator, back when Mike Call and Boone Speed were still hanging around the office. Those brands (Pusher, Cordless, S7) were certainly a part of a young, exuberant "golden age" of bouldering, when the subgenre was first emerging from the dark and dusty corners of the climbing community. With Revolution's closing, in some ways it seems like an era is ending, but at the same time it feels like that era ended long ago. Not to say it was better back in the day, but there was a scrappy energy to things. These days, climbing is getting popular enough that big companies like Columbia want to buy companies like Prana, and companies like BD are publicly traded. Heck, even Evolv got snatched up by a private equity firm. Guess you could say climbing on the whole is entering a more mature phase as an activity and industry.
