Event Tech Live (ETL), which was founded 10 years ago and has been held annually in London ever since, made a successful debut in the U.S. April 26-27 with Event Tech Live Las Vegas, held at The Expo at World Market Center. With a mix of the latest technology from both sides of the Atlantic and beyond, in addition to a wealth of interesting sessions, Event Tech Live Las Vegas was a big hit, according to Adam Parry, co-founder of ETL.
