Over the summer Nexstar's ABC station in Erie, PA (WJET-TV) Changed the first few minutes of their morning newscast slightly. Probably to compete with Lilly Broadcasting's NBC station WICU, who as of February 2014, was #1 in the morning.
One change, during the Forecast First segment on WJET, the meteorologist doesn't stand in front of the green screen anymore. He stays at the weather center. And at the end of the Forecast First he always says something like "it's time to start the show" This morning he said, something like, "it's time to start Monday's show" or something like that.
The 2nd change is after the open. The meteorologist sits with the morning anchor while they give a quick tease/chat about the stories coming up. Sometimes they have their one of their morning reporters/ weekend anchor sitting at the desk giving a tease of HIS story coming up.
There are two more changes as well. They now have mugs that have WJET's logo on it. Another change is, on September 1, they expanded their morning newscast from 5:30 to 5. Once again, probably to compete with WICU whose started at 5 for as long as I can remember. Our crap CBS station (and I mean crap) still remains lame and starts their newscast at 6 with an okay meteorologist and anchor. (Our CBS station is WSEE if you want to look it up)
I have only seen the first 15 minutes of the 6:30 edition so I don't know if it varies from any other editions. (Probably not because they aren't that creative in the morning)
Our FOX station WFXP which is operated by WJET has a morning newscast from 8-9am, which according to wikipedia, has aired since September 2007.
