I don’t know about split screening sports with breaking news, but IIRC (If I Remember Correctly), back on a Saturday afternoon in 2013, severe weather was coming through the Greater Atlanta, GA area. The NBA Playoffs were going on at the time on ABC affiliate WSB-TV Channel 2. I wasn’t watching the game at the time. I was listening to the radio instead. I was in my bedroom. A tornado warning was issued for east Cherokee County, GA & east Cobb County, GA. WSB Radio had their news director Chris Camp come in & announce a tornado warning had been issued for those counties. My fraternal sister & brother-in-law were visiting my mother & myself. My dad was out of town on a business trip. My sister tried to get me to go to the basement while thinking the warning applied to all of Cherokee County, GA. I turned on my TV while listening to the radio to get the alert statement from WeatherScan. WSB Radio’s chief meteorologist Kirk Mellish was out of town. When Chris Camp was done talking, WSB Radio went to outsourcing the severe weather coverage from WSB-TV’s severe weather team known as Severe Weather Team 2; This is now the radio station’s plan for every time there’s severe weather in the area whether Kirk Mellish is in town or not. I went to the den. I saw my mother, sister, & brother-in-law in the den. They had the TV on WSB-TV featuring 2 of their meteorologists, chief meteorologist Glen Burns & meteorologist Brad Nitz. It showed the radar on the TV with the alert zone that was under the tornado warning. We dodged a bullet thankfully because my parents & I live in SW Cherokee County, GA. We kept the TV on anyway for a good while. A couple of times, WSB-TV did put a square screen of the basketball game on the center right hand side of the screen. They could have done a full split screen, but they didn’t. Glen Burns was undecided on whether or not he wanted to return to the game already in progress. Eventually, from what I could tell, Glen Burns & Brad Nitz went all out and didn’t bother returning to the game already in progress. If they did return to the game already in progress, I don’t know about it. My mother changed the channel and that was the end of it all. Anyway, that is all.
