Rob Marcus, set to become Time Warner Cable’s CEO at the start of the new year, has tapped Dinni Jain, former president of cable operator Insight Communications, as chief operating officer.

Jain’s appointment comes amid reports that other cable operators — including Comcast, Cox and Charter in conjunction with John Malone’s Liberty Media — are evaluating deals to acquire or merge with Time Warner Cable.

Time Warner Cable completed its $3 billion acquisition of Insight in 2012, after which Jain left the company. In his new role, Jain will report to Marcus, who will become chairman and CEO on Jan. 1 following the retirement of Glenn Britt.

Jain, set to join TW Cable effective Jan. 13, will oversee operations of three main lines of business: residential services, business services and media sales. He also will be responsible for TWC’s technology and network operations, product development and content acquisition functions, as well as news, local sports and regional sports networks, including Time Warner Cable SportsNet.

“Dinni is a proven leader, with more than 20 years of experience in successfully operating cable systems,” said Mr. Marcus. “He has a great track record and shares my commitment to creating a performance driven, customer-centric culture at Time Warner Cable.”

Before joining Insight in 2002 as CFO, Jain was group managing director for strategy for cable operator NTL Europe.
