When an independently owned, and hence lesser known brand is bought by a larger company that easily appeals to the mass market. A comonopolous takeover results in the original street cred of the lesser known brand to be completely annihilated.
However, what it loses in independent kitsch, the new parent company find the deal extremely lucrative as they can now produce a cheaper product in bulk and market it to throngs of generic people everywhere.
Nike knew they would have a comonopoly when they bought Converse.
Kraft preformed a comonopolous takeover of Cadbury.
