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 soon begin putting its name in place of Insight's on buildings, uniforms and customer mailings. Other changes will come later.“Before you own a company, there's only so much information you can learn," says Time Warner spokeswoman Mary Jo Green. "Now that we own the company we can spend a little more time in getting to know things in detail.”Acquisitions like this tend to have a few side effects. Service may change. In this case, Time Warner is a larger company that could potentially bring new technology and channels to the area. And service changes are often accompanied by pricing changes. There will also be a change to staff. Some positions have been made redundant and could be eliminated.“We've already scheduled calls, operations calls, so that we can learn about how things are run here," says Green. "Kentucky will now be part of what Time Warner calls its west region. There will be some integration going on over that. It doesn't happen overnight.”Green says until Time Warner completes its review of Insight, she can't say what will change or when.
