The review, which is being handled by the AAR, does not affect the £1m media planning and buying account for BBC Magazines' activities in the UK, currently handled by Omnicom's PHD.
BBC Worldwide, which includes global TV sales, magazines and digital media, spent just over £7m on advertising in the 12 months to the end of June, according to Nielsen Media Research. A BBC spokesman confirmed that the organisation is holding chemistry meetings with media agencies this week, as it looks to appoint an agency to handle planning and buying for its Global Channels division.
Global Channels, which launched 18 months ago, covers wholly-owned channels BBC Prime, BBC Food and BBC America, as well as a range of themed channels - including BBC Entertainment and BBC Knowledge - which are being rolled out globally.
The BBC is reportedly looking at taking the sales for BBC America, currently handled by Discovery, back in-house.
BBC Worldwide has seen a three-fold increase in profits over the past three years. It posted record profits for the 12 months to 31 March this year, with a pre-tax rise of 24% to £111.1m, including a 5% rise in international sales to 46%.
