Sinclair Broadcast Group, which operates six broadcast television stations in Chattanooga among 173 stations it owns nationwide, is buying Tribune Media for about $3.9 billion.
The purchase announced today will boost number of local TV stations Sinclair owns or operates to more than 200.
Chicago-based Tribune owns or operates 42 television stations, including KTLA in Los Angeles and WPIX in New York, and it owns a stake in the Food Network.
In Chattanooga, Sinclair bought WTVC-TV, the ABC affiliate that broadcasts on channel 9, in 2011. Four years later, Sinclair also purchased WDSI-TV and WFLI-TV.
Combined the Chattanooga Sinclair stations include WTVC-TV9, The CW Chattanooga, MeTV, myTV and the WeatherNation.
