After the past general view of the industry, it would be interesting to know names. Who is in charge of those processes in the UK? Which companies are the bigger owners and players of the British advertising industries?
From the biggest world companies to the individuals this is the big picture:

Most large agencies had spread their specialised in-house departments as separate agencies. As the number of individual agencies has increased, ownership of those agencies has concentrated. Now there are many mergers and acquisitions, and a small group of holding companies at the top of the industry. (Adbrands.net, 2010).
According to Adbrands.net and Campaignlive.co.uk, there are now 5 major international advertising groups who control an enormous number of adversiting agencies globally, that notoriously influence the UK industry:
Omnicom, WPP, Interpublic, Publicis Groupe and Havas.
Then at next level, there are a small number of mid-size holding company groups; in the UK the are:
Omnicon:
Abbott Mead Vickers BBDO
DDB London
tbwa london
WWP:
JWT RKCR/Y&R
Ogilvy Advertising
Grey London
United
Interpublic:
McCann Erickson
Lowe
DraftFCB
Publicis:
Bartle Bogle Hegarty (UK)
Publicis
Leo Burnett
Saatchi &Saatchi
Fallon
Havas:
Euro RSGC London
Euro RSCG Fuel
Next, there are "micro-networks": Similar to the major networks, but they operate a far smaller network, usually in key regional centres. They generally offer custom made service for more demanding multinational clients (Adbrands.net, 2010).
There is a final step: standalone companies, could be independent or owned by one of the major groups. They tend to operate only in their own country, although they may have links to agencies in other markets. These are what we know as advertising agencies.
