Top of the Pops and the BBC Radio 1 chart will be sponsored by Coca Cola next year.
The drinks giant has signed a multi-million pound deal to be the sponsor of the pop charts.
It is interesting because the BBC does not normally carry adverts of any kind, because it is paid for by the public from the licence fee.
But the BBC has insisted the deal, and mentions of Coke on air, will stay within its guidelines.
It would only be seen by the public in the same way that the BBC showed Renault, who sponsored Prom in the Park, the company said.
Rival cola company Pepsi used to sponsor the Commercial Network Chart, now called Hit 40 UK.
The last company to sponsor the official chart, Worldpop, ended its deal two years ago.
