Unbundling
Unbundling is the process of breaking up packages of products and services that were previously offered as a group, possibly even free. Unbundling has been called "the great disruptor". Unbundling prices and extending choice are generally processes seen as favourable to customers.
In the context of mergers and acquisitions, unbundling refers to the "process by which a large company with several different lines of business retains one or more core businesses and sells off the remaining assets, product/service lines, divisions or subsidiaries".
