Apple has rarely released sales figures on particular models of products they offer, but I have to imagine they shipped at least hundreds of thousands of its two Apple LED Cinema Displays (24-inch and 27-inch) based on the number of people who want to connect them via USB-C to a 12-inch MacBook or a 2016 MacBook Pro.
I purchased several adapters and cables that can take the LED Cinema Display's Mini-DisplayPort (not Thunderbolt) and convert it into something that passes over USB-C in a compatible chain that allows you to connect to the USB-C equipped MacBook and 2016 MacBook Pro. My testing shows three affordable and viable options, plus a reasonable option for a full-featured USB-C dock that requires just a simple adapter.
