As revealed on prweek.com this Wednesday, 15-year Ogilvy stalwart Anderson - a US national - will join on 1 November as group director of comms.
He will report to Sky CEO James Murdoch and oversee corporate comms, programme publicity, public affairs, CSR and internal communications.
He joins as BSkyB bids to retain its rights to broadcast FA Premiership live football matches. It is also chasing ten million UK subscribers by 2010. Anderson replaces Julian Eccles, who is leaving after five years.
He told PRWeek: 'I am thrilled to be joining Sky but I have loved it at Ogilvy. I wasn't out there actively looking for a job.'
Anderson's exit is a blow to Ogilvy, which also lost European CEO Paul Barber to Tottenham Hotspur FC earlier this year.
Ogilvy global strategy and planning MD Steve Dahllof has temporarily relocated from Washington DC to London. He and global CEO Marcia Silverman are now recruiting for the role of European president.
