thousands ? millions ? or billions ? in a day ? do you know ? any resources ? I just want to know the earning limits for marketers.
The sky is the limit. This is all I could say. The numbers will be massive, even if you take the amount spent on online shopping alone.
This is a pretty redundant question. It's a lot is all you need to know, more money than any person could ever spend realistically. Now find a way to get some, that's a more important question. But if you really want to know, it was $20,000,000,000,000 in 2000 I think (not sure this is actually what I think it is http://www.worldwatch.org/node/1783). $54,800,000 a day? Seems low for worldwide, but not sure.
"thousands" .. erm no. Is it like 6 billion people in the world? The UK has 60 million alone. Average person probably spends at least £15 a day right. That's $30. So in the UK alone you're getting 60,000,000 x 30 dollars a day... But that's really a rough estimate and my numbers are most likely wrong. Basically, the number is stupidly large.
