NEW YORK, Sep 21, 2021/MediaPost/ — Publicis Groupe’s Starcom is the top global media agency in net new business activity for the first half of 2021 according to a new analysis from agency research firm COMvergence. The net new business figures cited below are billings numbers and include retentions and also factor in business that was lost.

During the first half of the year COMvergence assessed 1,940 media account moves and retentions across 46 countries totaling $13.2 billion, an increase of 27% over the same period in 2020, when review activity was suppressed by the pandemic. The US accounted for 38% of the total spending assessed.

For the period Starcom won $2.2 billion in net new business. That includes $1.2 billion in retained business where the agency was an incumbent in reviews. The agency’s biggest win was auto giant Stellantis–formed earlier this year with the merger between the Italian-American Fiat Chrysler Automobiles and the French PSA Group.
