The UK Door Drop industry saw declines in 2009, with advertising expenditure down 8.9% and volumes falling 14.1% to 7.763 billion items. The average weight of door drop items also decreased by 14% from 2005 levels. As a result, the total weight of door drop material delivered fell 44% from 221,565 tonnes in 2005 to 124,808 tonnes in 2009. Declines were driven by factors like improved targeting, growth of digital media, and the economic recession.
