Yahoo Ads, how long until they show up?

[Vvoajpaaa]

Hey everyone
I was wondering does anyone know how long it takes for your Ad to show up on a yahoo search after creating the ad?

I had to look for alternatives sense google always puts new ads 'under review' which is there way of saying..... see you in

about 3 weeks.

Any information will be helpful.. Also does anyone know how long it takes for Bing to do the same thing?

Thanks
