I was speaking yesterday with Cheryl Platt of EFX Media, a terrific marketing and media company based in Alexandria, VA. Cheryl is Senior Business Development Executive at EFX and, more to my immediate point, thinks about things a lot and creatively. Both Cheryl and EFX create targeted internal and external communications strategies for companies, with a great strength in video. On this point, I was asking Cheryl about her iPhone, or as Cheryl calls it, her “third screen”. I had never heard the term, so I wanted to learn more.
