Nigo started using USM hallers for his home and studios and popularized it way way way before the other names in the video title did. im sure they were all just following Nigo. as you could only see them using USM in recent years. Nigo probably started using USM to style his home and studios way earlier but i first saw him using USM was in 2005 in a magazine. i believe it was Nigo who made USM popular.( at least in the fashion industry) before Nigo,i didnt see too many designers use USM. so i think Nigo deserves way more credit than anyone else for popularizing USM
