I had no idea that Real Estate Advertising accounts for 17.7% of all online ad spending and will double by 2010 to 32.1% according to Borrel Associates.

"The “2006 Update: Online Real Estate Advertising” reports that online real estate ad spending has risen less than 4% since 2001. And while the number of homes on the market has increased by almost 41% over the past year, real estate ad spending across all forms of media has remained almost constant at $11.6 billion.

The combination of a saturated home sales market with the decline in print classified ads will cause online real estate ad spending to grow to about $1.7 billion this year, and it will reach about $3 billion in 2010. While spending on online real estate ads increases, the report predicts that the total real estate ad spending will actually drop to about $9.5 billion."

I’m wondering what the online advertising market will look like in 2010 if a third of the advertising is about real estate.   I think that’s excessive.
