It looks like WFLA is ready to take advantage of having WTTA as its sister station and will do so in form of an hour-long, nightly primetime newscast.
Starting Monday January 4th, 2016, WFLA 8 will air an hour-long primetime newscast at 8:00pm for its sister station, WTTA 38 which is known as Great 38 and is affiliated with My Network TV. NewsChannel 8 at 8:00 on Great 38 will be on the air nightly, including weekends, creating Tampa Bay’s first and ONLY nightly primetime newscast at 8:00pm.

This will delay MyNetworkTV programming by one hour (from 9-11pm). AFAIK, WTTA is the first MNT affiliate in the Eastern time zone to do this. Do you think any others will follow suit?
