A lot of it, IMO, has to do with your local stations and the national TV networks themselves. Your local stations can probably get TOS or TOS-Remastered if they wanted to, but if they feel more people would rather watch TNG, then that's what they'll go with.
The same is probably true for any show that has been in syndication. I think it ultimately comes down to a station or network programming director, who may not even know the difference between TNG and TOS, but simply felt that TNG will draw the bigger audience. In other areas, you may have programming directors who sought TOS for their own reasons...
