The new media age Top 100 2012 guide is to be published in May and opens for entries today.

The annual guide, which ranks the UK’s top digital marketing, design-and-build, technical and media agencies, is ranked by fee income from digital activity.

Launched in 2000, the Top 100 is the definitive guide to the interactive agencies marketplace.

Agencies will be ranked by their fee income (or billings for media agencies) and the financial information supplied will need to be signed off by a finance director or auditor. Deadline for entries is 1 March 2012.

A preview copy of the form can be downloaded below. To enter click here.

The Most Influential People table was topped by Wieden & Kennedy global interactive executive creative director Iain Tait.
