 Public broadcasters in France supplement their licence fee income with revenue from advertising, but changes in the law in 2009 designed to stop public television chasing ratings, have stopped public broadcasters from airing advertising after 8 pm.Between 1998 and 2004 the proportion of France Télévision's income that came from advertising declined from around 40% to 30%.To keep the cost of collection low, the licence fee in France is collected as part of local taxes.
