Virtual Assets have become Real Assets
As Internet traffic has reached astronomic heights, so has the business with digital or virtual assets. The world is digitally as connected as never before, big business has discovered the potential of the Internet and has moved advertising dollars into Internet advertising full throttle. As a result, corporations advertising expenditures have skyrocketed. For webmasters, this means that the revenue potential has gone up significantly.
For domains and websites, traffic and revenue are tied to each other. They are directly proportional because the amount of traffic that your blog or website generates translates into higher revenue (in many cases, anyways). As a result, prices for valuable domains and websites have generally gone up, sometimes a lot with single domains having changed ownerships for millions of dollars.
