Despite attention drawn to larger agencies in the wake of International Creative Management’s recent acquisition of the Broder Webb Chervin Silbermann Agency, mid-sized and boutique firms are still competitive in getting their clients booked on TV series, online TV research firm TVTracker.com found in a recent report.

In a ranking of Hollywood agents based on the number of clients booked as series regulars on broadcast and cable series for the 2006-07 season, agents at mid-sized firms outpaced larger competition.

Innovative Artists’ Craig Shapiro is ranked No.1 with 15 acting clients staffed as series regulars, followed by ICM’s Dar Rollins and the Agency for the Performing Arts’ Ryan Martin, both with 13 acting clients staffed as series regulars. The Gersh Agency’s David DeCamillo and Leslie Seibert are tied with 12 clients each.

The report, which does not estimate agency commissions, packaging fees or revenue, was complied as the ICM-BWCS was acquired. But the agencies are listed separately in the report.

Among literary agents, or agents that represent TV writers, Endeavor takes the top three agent spots for the most clients staffed on 2006-07 series.

According to the TVTracker.com report, Endeavor’s Ari Greenberg ranked No.1 with 46 writing clients staffed, followed by his colleagues Richard Weitz (39 clients) and Greg Hodes (36 clients). William Morris Agency’s Aaron Kaplan followed with 35 clients, while Endeavor’s Paul Haas and the Rothman Brecher Agency’s Robb Rothman tied with 30 clients staffed.
