It would be wasteful to upload the full size image only to throw most of it away. JPEG compression is very cheap, especially at low resolutions (I assume that image search uses a pretty low-resolution source image). Doing it this way is actually what I would do for best user experience. (Not saying that they aren’t doing other malicious things, but doing the resizing on the client is actually a good idea)
If you don’t need to watch Jeopardy live it is pretty readily available via torrents. Probably in better quality and without ads.
Sports are much harder to find. There are trackers but they are much harder to get into and I can’t attest to the completeness (I’m not really into sports) and watching it live is probably more relevant.
