It was done for a time, but there are serious limits on how much data a satellite can allow to be streamed through it, and limits on speed. Fiber optic direct lines are much, much more faster, and can handle far larger volumes of data.
Thanks; I had no idea it was that wideapread.
The other problem with satellites is latency (the time it takes the signal to move from point A to point B). Telecom satellites orbit 26,000 miles above the equator, so the minimum time for the round trip will be ~0.3 seconds but much longer at higher latitudes. Using cables it’s usually less than 0.025 seconds.
