PLSN marks its 10th Anniversary with the Feb. 2010 issue. In that time, production companies have morphed, but the crew lists and gear lists haven't changed as much. The most significant changes, in terms of technology, is the integration of video, LEDs, media services and networking in live event production. But one thing that hasn't changed, despite a half-dozen redesigns to its graphic look, is the magazine's commitment to service and innovation , personified by the founder and publisher, Terry Lowe.
