There are 3 main frame rates we are used to seeing: 24 progressive, 30 progressive and 30 interlaced.
24 prog is truly 24 full images every seconds. It has been used in movies forever, and we call it "Film look". Television shows have started using it more frequently for the past 10 years (but higher budget TV shows that shoot on film have been using it for decades.)
30 progressive is more rare, it is 30 full progressive images every second. It is a little hard to see a difference for common people, it is fairly close to 24p. Television have been using 30 frames per second because of the frequency of North American electricity (60 Hz)
The really bad frame rate is 30 interlaced, which is basically 60 half frames played every seconds. Even though they are only hald frame, each of those half frame represent a different moment in time, so the movement is really fluid. This frame rate has been used forever for sports, variety shows, and it was the frame rate for the early digital cameras (MiniDVs). This is why it has been associated with low budget.
Personally, I'm afrait of what 48 FPS will do. We fight so hard to avoid this feeling in post production, I wonder how people will get used to it.
