Laserdisc has analog video because the physical pits and lands on the disc directly represent the continuously varying video signal, using frequency modulation (FM) where the length and spacing of these features change to encode brightness and color information, much like an old analog TV broadcast, rather than discrete 1s and 0s like CDs or DVDs. A laser reads these varying pit lengths, creating a fluctuating signal that's a direct analog of the NTSC or PAL video signal, which is why it looked great on CRT TVs.

Key Difference from Digital:
LaserDisc (Analog Video): Pit length/spacing = frequency of signal (continuous).
CD/DVD (Digital): Pit length/spacing = binary 1s and 0s (discrete).
