Concorde was a multibillion dollar government research programme which built hardly any aircraft and still had to give away some of them for £1 due to absence of commercial demand. Noise, lack of range and cost meant that even after 14 aircraft had been effectively given away, they spent most of the time on the ground because of the difficulty of finding more than a couple of viable routes. Sure, some people paid for tickets, but it's a stretch to call that 'commercialization' in the context of the impossibility of ever recovering the programme's losses.
