Angled Pickups?

I have never full understood the benefits of angled pickups. Such as the bridge pickup of most Stratocasters. I sopose it's more of a sweet spot to catch string harmonics, or something like that, but if that the case, then how come the majority of guitars dont positions their pickups with angles? Is is because only single coil bridge pickups should be angled, or is just what Fender did to be different.

I believe (tho i could be wrong!) its the reason strats and teles have there famous 'twang' because the pick-up is angled toward the bridge where the strings are eeerr more twangy

They're angled so that the treble side of the pickup is closer to the bridge to pickup more treble... and the basss is farther away so it can pick up more bass..... If they were straight there wouldn't be much bass in the tone...

oh gotcha, thanks alot. :)

also theres slanted to the backside pickups...
fender venus is a good example for them...
courtney love designed it, n god knows what the heck she was thinkin...
less bass, less treble?
weird...
