ClickZ Online Marketing Expert website had an interesting article a few months ago, written by Kate Kaye, and highlighting the research firm of Borrell Associates' report stating that online real estate ad spending is expected to grow from $2 billion this year, to $3 billion by 2010!

It's interesting to note that the report also states that agents who have been in the business for a substantial amount of time are much slower to jump on the internet ad and budget bandwagon than their less seasoned counterparts.
