Grandpa, I've got this assignment to do. My teacher asked us to do a report about radios and television through the decades. Do you know anything about this stuff? Dave asked his grandfather.
In the 1980s, around the time that you were born, TV changed once again. Music videos started to be broadcast on TV along with what were known as mini-series, both gaining popularity during the 80s.
Now in the late 80s and 90s, programming on television has basically remained the same, but the way that the TV gets into peoples homes has changed. People are no longer limited to receiving signals by antenna, but now cable broadcasting has become popular, along with satellite transmission. The use of satellite means that TV signals can be transmitted around the world with the use of very little or no cables. This is done by sending the signal over what are known as microwaves to satellites that orbit around the earth."
Grandpa, I think I've got more than enough information. I'm sure to get an A++ now. I want to start my report right now. Thanks, grandpa.
