Why are television cameras so big

Why are cinema cameras so big? [closed]

There are a couple of factors that contribute to this, but I'll break it down for television cameras as that seems to be the question.

The lens: in many cases the camera is not as big as only a huge lens can be. The next time you're at a sporting event, check out how far the cameras are from the actual field but still can get a great shot.

Viewfinder: Studio cameras usually also have large viewfinders (which are actually more like small televisions), as is the case with small eyepiece viewfinders or 3-inch screens on your DSLR. Note the large unit on the top back of the camera in the picture.

Additional Features: In a live TV studio that implements a multi-camera setup that is broadcast through a mixer, some additional features are required to watch a broadcast. When editing videos, you have the luxury of correcting things like color in post-production. You don't have that luxury in a live setup. To avoid dropping images when switching, and to make sure the colors are constant across multiple cameras, the cameras have things like Genock and Remote Color Correction etc.

Teleprompters: Some large units also have built-in teleprompters and queue lights that make them appear large, but in reality what you see is different.

Old Gear: In some cases, studios invest in high quality equipment and expect it to be for many years. Some pieces of equipment are simply large and bulky, as they come from a time when it was the smallest material available.

Don't forget the "pro" factor. Psychologically, large cameras are perceived by the public as a sign of professional technology. Because of this, many companies have high-end video cameras that differ from low-end video cameras in only a few minor features, but are twice the size and contain a lot of extra empty space. (No, I'm not kidding. I can provide examples if you want.)
