Many suppliers of so-called junk food will have to find alternative ways of marketing their wares following a landmark decision by advertising watchdog Ofcom.
It has decided that advertising of all high fat, salt or sugar products during kids' television programmes should be banned. The ban will also cover programmes that have particular appeal to under-16s.
Analysts believe the ban will either force suppliers to reformulate their products or change the focus of their marketing. This could lead to a greater focus on in-store advertising and promotional activity, and could see suppliers developing closer relationships with retailers.
