Time Warner Cable has completed its purchase of Insight Communications, and changes to branding and service will begin over the next few months. Time Warner paid $3 billion for Insight and will absorb more than three quarters of a million Insight customers in Kentucky, Ohio and Indiana. Time Warner will also take over Insight's operations. That means some jobs will be redundant and those positions will be lost. Time Warner spokeswoman Mary Jo Green says it's too soon to tell how many employees will be let go.
