Although we'll have to wait for Leica's statement for the full story, I'd hazard a guess that the comments posted by tiltody are pretty much on the money. Almost instant global communication services and rapid delivery systems have meant that many companies have consolidated and gone down or are contemplating going down the same road.
One example, although not a company, is the UK Diplomatic service. The government has been questioning whether they need to completely overhaul it as the days when communications back to Blighty took months, and Ambassadors on the ground made decisions, are long gone.
