Licensing: Several TV-Stations (NBC) in Many US-States Copied My Video Without My Permission

Hello,

I do have a question about copyright of Videos.
I have put a Video some 5 years ago online, which by now have more than a quarter of a million clicks,
399 Subcribers, and 253 Comments, 306 likes so fare.

Just recently I had to learn, that several TV Stations and other media copied my video and used this my video for their own purposes.

How can I make them stopping using my video, or furthermore make them to delete parts of my video.

Thanks for your answers....

Grüsse... Marc-64
