IP Showcase a major NAB success for MNA member companies

Media Networking Alliance, Bothell, Washington, USA, 16 May 2017. Terry Holton, Vice Chairman of the Media Networking Alliance (MNA) – the non-profit trade association, established to promote the adoption of the AES67 standard – has described the participation of more than 10 MNA member companies in the IP Showcase event, held throughout the recently concluded NAB Show in Las Vegas, as “the most impressive and effective event the MNA has participated in”.

As a member of the IP Showcase Board, Holton – aided by MNA Marketing Working Group Co- Chair Angi Roberson and MNA Administrator Tina Lipscomb – managed the MNA’s role in developing and staging the IP Showcase with eight other broadcast and professional audio industry organisations, and coordinated the participation of MNA member companies in the event during NAB.

“I would like to thank and congratulate all of the MNA members who participated in the very successful IP Showcase event,” said Holton. “I believe that all members who were involved in the IP Showcase would agree that this was the most impressive and effective event the MNA has participated in, since its inception nearly three years ago.

“The IP Showcase was a collaboration between a number of highly respected and influential industry organizations and it was a great honor for the MNA to be included among them.”
