Depends on the vehicle. Chrysler products that use the 3.7 and 4.7 engine use copper plugs and they need to changed every 30K miles. Most engines that use platinum plugs are good for 100K but I wouldn't leave them in that long. Most engines now have aluminum heads - replacing plugs at 100k means the plugs are most likely galled in place and you stand a good chance of removing the aluminum threads while turning out the steel plug. Also worn plug make the coils work harder and the individual coil on plug wires are very expensive.
I just removed the plugs on my son's "new" 1996 Ford F150 with a 5.0 engine. Thankfully those heads are steel because the iridium plugs were original - a full 20 years old with 130K miles on them and they looked it. The gap was massive and the plugs all looked burnt.
