Specialised handset vendor Doro is attempting to prove that a successful business model can be achieved from offering smartphones and multimedia content to the senior market.  “We are building an ecosystem towards elderly people where different partners include those in the news publishing category, or games; even Angry Birds can be an interesting game for them, and also crosswords, scrabble, these types of activities,” Doro CEO Jérôme Arnaud told Mobile World Live in a new video interview. “We are also looking at partners for banking applications and so on. We are always trying to determine those [partners] who are most relevant to the elderly.”
