Back in the day, when I used to write about film, video and TV, the industry magazine I had the highest regard for was Promo. It was a neglected and unloved afterthought to Music Week, but it was a simple digest of news about who had made what videos, for how much and with who. It was edited by a guy called David Knight who knew his market inside out. Our magazine (Creation) had a following in the high end commercials market, but if I even dreamed I had as much stature amongst the creative community of Soho as David did amongst the record company commissioners and promo directors, then I would wake up and apologise.
So, as is the way of these things Promo has closed as a magazine, but he's set it up as a site, here. Go and visit it if you have the slightest interest in music video.
