Why do people watch TV or play with their computers with the lights off ?

I've noticed some people watch TV or use their computers with their lights off . I've never thought about it -- I just naturally have the lights on . Didn't Thomas Edison invent the light bulb so we didn't have to sit in the dark ? Isn't it easier to see the keyboard with the lights on ? What if you want to write a letter while you're watching TV ? Isn't watching TV or playing with your computer with the lights off basically pointless .?

It's not pointless. Often it will give dramatic effect to a movie. It also makes it easier to concentrate when everything else BUT the tv is drowned out in darkness, which makes that movie a focal point. Also, glare on the screen is another reason why people will close the curtains and turn the light off. My tv and computer screens are hell like that. With less light, you don't strain your eyes as much.

But once you get used to the feel of a keyboard, typing becomes instinctive and you don't need to see what you are pressing. If the game requires complex keystrokes though, people will be more likely to use more light.
