At least in the United States, it's a very, very common expression for "I watched TV for a short time".
I hope that helps.

I came across this sentence when I was surfing our forum.
My questions: What is the meaning of " I watched a little TV"?
Does it mean that "I watched TV for a short time" or it mean "I watched "a little TV" "?
Thanks so much.
It usually means you watched TV for a short period of time.
If a physical dimension is intended, one might say "I watched the program on a little TV set."
