Insight Communications was an Americanmultiple system operator (MSO) that served the states of Kentucky, Indiana and Ohio. Until its purchase by Time Warner Cable in 2011, Insight was the ninth largest cable operator in the United States with 760,000 subscribers.
On August 13, 2011, Time Warner Cable announced its purchase of Insight Communications for $3 billion. The sale will create cost efficiencies of approximately $100 million annually through savings on programming expenses and other cost reductions, with the bulk of the savings realized within two years of the close of sale. With Insight's 2011 conversion of its television services from analog to digital, Time Warner Cable expects Insight to have lower capital requirements of 10-12% of revenues upon completion of the acquisition, which is subject to approval by the Federal Communications Commission and Insight franchisees. The merger was completed February 29, 2012.  On March 9, 2013, letters were sent to Insight customers informing them that starting in June 2013, Insight Communications will be completely absorbed, and Insight service will be replaced by Time Warner Cable.
