This of course is proof that TWC is trying so hard to be more like every other cable channel rather than being a unique, valuable place where viewers go for something different.
You're right, and it's sad. There is hardly any uniqueness amongst cable channels anymore. They're all falling over themselves to be exactly the same as everyone else.
In any case, I'm on satellite and see no LDL on screen during the commercials. During the normal programming, a LDL showing weather info for select cities appears.
As it is right now, LDLs over commercials are errors, not the norm, so no one should really be seeing them... yet. I strongly dislike when my IntelliStar 2 goes down (or just doesn't get cued - happens too often) and I see the national LDL instead. It's as useful to me as the "Travel Cities Forecast" national feed local forecast from ages ago - one line in the whole segment
may be useful, but not very, and you have to wait forever for it to show up.
