As I mentioned in my SEL post, the category “classifieds” (which includes verticals jobs, cars and real estate) is the third largest Internet ad category, capturing 18 percent of online ad spending according to the IAB, behind only display and search. Traditional U.S. directory and classifieds ad revenues were worth more than $30 billion in 2006.
Jobs = career fairs.
Cars = car shows.
Real estate = home shows.
Just making some connections in my head.
