A lot of you say things like "I would boycott those companies" but in reality you would do exactly what big advertisers want you to do that's why they do it . People spend billions of dollars every year just trying to figure out what would make you buy thier product and buy a lot of it.Advertisers know what they are doing and if they dfecided it was worth it to put a pepsi logo on the moon a lot of research would have gone into that and although there would be a few people out there that really did boycot them but the brand recognition would make them enough money that it wouldn't reallt matter.And besides all that it would not happen overnight it would happen slowly enough that by the time there was a full time advertisement on the moon you wouldn't even think about how wierd it was thats what is happening right now eveywhere you look,heck right now the NBA is talking about selling ad space on players jersies I'll bet when the first stadium was named after some big corporation nobody saw that coming,and one day when every athlete looks like a stock car nobody will think anything of it. The same will apply to the moon they will sneak it up on you so slowly you wouldn't even notice.

How long though would it take to see billboards in space. Yes probably in 100-200 years people can take vacations in space probably but just how long could this be?

And for advertising on billboards will they something to keep them still or would they orbit around earth?

and yet it is funny that they are bothering with this at all think about it the billboard would have to be at leat 500-1000 square miles might be wrong on that size plus the money that would have to go into keeping that thing afloat in space as well.

and also in dream land man will soon be able to breath in space without oxygen to

That's mad! It would be horrible if there were huge advertisements in the sky! I never buy anything from an advert unless I want to buy it anyways. I think it's just dumb if companies would do that. Sure, it might help their business, but I think if people saw an advert in the sky they would be turned away from buying their products. I would.

That's the thing if you know anything at all about advertising you that brand recognition is a very big factor possibly the biggest factor that determines what people buy.Doritos commercials aren't supposed make you want doritos they are designed to keep doritos on your mind,to make you think that you decided all on your own that you want doritos.You may think that you make your own descisions but advertisers don't spend all that money just to remind you that doritos exist everybody knows that,they spend the money to make think about it and think about it alot.

I'm pretty sure theres no possible way for them to be stationary, and even if there was it wouldn't matter because the earth is rotating so they would have to match that speed, which is crazy. Plus, they would want to reach the biggest audience possible so it would probably have to be moving all the time to achieve that goal anyway.

As for it having to be 500 square miles, you can see the space shuttle with binoculars. My brother does it all the time. The space shuttle is definitely not even a mile long. So I don't really think it would have to be THAT big. Just big enough so that you can see it with the naked eye. And if they just want it to be a logo, like the pepsi logo or something... it wouldn't need to be enormous.

I also remember reading a similiar article that was saying a type of advertisement in space would use projectors or something like that. So it wouldn't have to be a massive object, just a projector. I'm not sure what exactly it would be projecting on haha. I can't remember the source though. Maybe I'm just making it up...

I, for one, am very sick of this ad-saturated culture of ours. If only we could transport ourselves back to the 1880's when life was simple, and every wore long dresses and rode in horse buggies!

Anyway, I hope nobody decides to actually build a billboard in space; we already have too many clutering our highways. And, really, we have to many ads cluttering everything! The weirdest place for an ad I've seen so far: a sticker on a banana. It was the same size and shape of the typical Chiquita sticker, only it said, "Go see the Garfield movie!"

Seeing that made the thought of billboards in space a little less remote.

actually there are satelites in space doing this very thing right now so I'm pretty sure that is not much of an obstacle

I think this is a crazy idea. I am a comsumer and i don't want to look at the sky most of the time to find out what products are available at the atores. hehehe Looking up at those big billboards is already pretty tiring for me, what more for those advertisements on the sky.

The first problem to solve on this kind ob "billboards" is how to stop the lights/projector from beaming all the way to the space.

I guess most people, find products on the internet nowadays, and they are busy doing everything on internet at night time. so there would probably less market for those advertisments.

people living on Cities woul not see those billboards as well because they would be obstructed by hihg rise buildings, and yes, air pollution.
