ANALOG cameras?

These days is full of shopping sprees so no wonder my piggy has gone thinner...sob sob...
Anyway, that's not the point.
The point as you know is the title above.
While shopping with my mum sumewhere near Bishan, I chance upon this big electronic store.
I was browsing through the digital cameras sections to show my mum the cameras that I would like to have.
Yeah..then as we go around searching for it, the cameras were divided into digital and analog.
I was like.........HUH??
I retraced my steps and take a look at the word analog more closely.
DUH??!!
Then I look at the cameras under it.
IT is just TRADITIONAL cameras with the film and then u do point and shoot.
I was thinking.........arent they traditionally called cameras?
Furthermore, the word analog as the dictionary refresh my memory, is transmitting some signals across the frequency and stuff like TV and radios, some handphones..when has it become cameras?
IF.....
analog cameras and the cameras as we known in general are the same, then why bother to put analog in front?
WEIRD??!!
