Pharmaceutical conglomerate GSK has split their billion-dollar media planning and buying accounts between fierce rivals WPP and Omnicom, ousting agencies from Publicis and Aegis.

According to reports, media giant Omnicom is allegedly plotting the launch of a third digital agency, standing alone from incumbents OMD and PHD, to compete with Publicis and WPP.

Media giant Omnicom have announced a rise in pre-tax profits of $482 million (£316.7 million) in the three months to the end of June 2013, up 2.3% on Q2 in 2012.
