Cough syrup range Veno's has returned to TV screens throughout Britain for the first time in five years with a high-profile GMTV weather sponsorship package worth £1m. Running until March next year, GlaxoSmithKline hopes the five-month campaign will boost sales and create greater awareness of the brand through the cough, cold and flu season. Four new 10-second executions will precede weather reports three times a day, five days a week. {{P&P }}
