PlayNetwork has announced the expansion of its senior management team, adding industry veterans Brian Hirsh as Senior Vice President of Marketing, Licensing and New Media, and Walt Tatum as Senior Vice President of North American Sales.

Hirsh, the former president of Retail Entertainment Design, an entertainment marketing agency, spent the past five years concentrating on in-store media, out of home advertising, brand development and digital signage. He oversaw marketing, media relations, licensing, finance, and drove the strategic direction for the company. Prior to that, Hirsh was the director of national sales at DMX Music, a provider of media, music and entertainment for retail and hospitality brands.

Tatum was promoted to Senior Vice President of North American Sales after joining PlayNetwork in May 2009 as its regional sales director. Tatum will now oversee all direct, VAR and local sales channels within North America. Before joining PlayNetwork, Tatum was the Vice President and General Manager of sales at DMX Music, where he spent eight years, two of those years overlapping the time Hirsh spent at DMX Music. Prior to that, Tatum was the CEO of XTreme Motorsports International.
