Combined, Wrigley and Mars controlled 14.4 percent of the global confectionery market in 2006, compared with 10.1 percent for Cadbury, according to the most recent market share data from Euromonitor International.Cadbury (which is in the midst of spinning off its soft drinks as a separate entity) may now be looking at trying to buy Hershey, although the linked article says that state law in Pennsylvania may prevent Hershey being sold (which seems a bit strange).
This sort of transaction represents the flip side of the increasing concentration of retail channels. As retailers grow, their suppliers have to grow to be big enough to sit at the same table on terms of some sort of equality.
