The move to integrate WGN-TV with 24-hour cable news channel CLTV was announced Wednesday.
Tribune Broadcasting President Ed Wilson says it's an opportunity to expand the company's position.
The change will begin over the summer when all of CLTV's business and television functions will be moved into WGN-TV's Chicago facilities.
Reporters and photographers will operate in a single newsroom and report for both stations. CLTV will continue to be a 24-hour cable news channel.
Tribune spokesman Gary Weitman said it hasn't been determined if jobs will be cut.
He said the Chicago company will save money from the move, but that wasn't the motivating factor.
