You know the first time I decided a media outlet was pushing an agenda? When Fox News famously asked its audience as it went to break if Obama's fist bump was "a terrorist fist jab".
This isn't a "progressive" narrative; it's whatever narrative fits the interests of the company. Sometimes it's progressive, such as when it comes to social issues. Oftentimes it's conservative. I've yet to see CNN etc laud unions, higher taxes on the rich, universal healthcare, etc, even in stories they were reporting on where it would make sense (such as the high cost of private healthcare, or times it didn't cover something ludicrously expensive for someone because reasons, etc)
You could perhaps argue that they are more "woke" than "progressive".
