Earthlink chose Publicis Groupe's MediaVest USA Tuesday as its media buying and planning agency of record. Before switching to MediaVest, the Atlanta-based Internet service provider had its
media account with Horizon Media for the last three years. The creative account, which is with Crispin Porter + Bogusky, was unaffected. As part of the consolidation, MediaVest's sister company,
Halogen, will manage direct response television duties. -- D.K.
