60 Min Or 90 Min Boils

[Steve]

Same questions as the mash question. Ive noticed recipes that say 60 or 90 min boils? Why so? What do you do? What benefits do you get from the 90 min boil. Sorry for all the questions - just curious?
Cheers

Longer boil will help darken the wort.

Different way of bittering maybe? Using less of a particular hop but boiling it for longer to acheive the same IBU's?
