Replying to Life Cycle of Ski Companies

Lately, smaller companies that have been in the game for periods of time have been losing all of their sponsors, and subsequently losing revenue. Some prime examples are APO and Fat-ypus, where practically their whole team has gone to Faction or elsewhere. In spite of this, new companies have emerged, including Revision, HG, and Vishnu (not to mention TBK ski co.). Is our industry dominated by 2-4 big companies, or is this just the life cycle of ski companies?
