The nature and delivery of our client work has evolved significantly. Most of our major clients required rapid support in developing relevant communications, with new campaigns being developed in days rather than months. Our investment in production through Hogarth, combining leading-edge technology with a wide geographical footprint, has been a strong differentiator in this regard. We have also been working with clients to re-plan their communications spend, redirecting resources to alternative channels and maximising their media return on investment. Work on ecommerce and omnichannel services has also ramped up significantly, with ongoing ecommerce engagements with 8 of our top 10 clients.
Our PR businesses have held up relatively well (revenue less pass-through costs -3.6% and like-for-like revenue less pass-through costs -4.5% in the first half), as clients have sought advice on how to engage with their own stakeholders. We expect future demand for our experience, commerce and technology services to be very strong, with clients looking to adapt rapidly to permanent changes in consumer behaviour. On the other hand, we have seen pressure on some project-based work in branding and identity as clients look to cut costs.
Our new business performance has continued to be very strong, In the first half we won almost $4 billion of new business, with very few assignment losses, and this is testament to the success of our new strategy: WPP now has fewer, stronger agency brands working better together. We are seeing very strong levels of collaboration across WPP, with most pitches involving multi-agency teams with strong co-ordination and support from the client, new business and technology expertise we are building in the centre. Key wins included Intel (global creative), HSBC (global creative), Unilever (China media) and WW (global integrated creative and media).
Our sector exposure has also delivered a more resilient performance. Within our top 200 clients, 56% of revenue comes from companies in the consumer packaged goods, technology and healthcare & pharma sectors, which were the least impacted by COVID-19. Their combined revenue growth in the first half was -0.6%. Within retail, financial services, telecom, media & entertainment and other clients, representing 22%, revenue growth was -4.9%. The sectors which suffered the most – automotive, luxury & premium and travel & leisure, which together comprise 22% of top 200 client income – saw a revenue decline of 12.9%.
Our commitment to creativity also continues to be reflected in the industry recognition our campaigns attract. In June, WPP was ranked the most effective marketing communications company in the world in the 2020 Effie Index. It is the ninth successive year that WPP has received this award. The Index, the world’s most comprehensive global ranking of marketing effectiveness, lists companies that create the most effective marketing and communications ideas in terms of measurable business results for clients. In the same month, the Cannes Lions International Festival of Creativity named WPP as holding company of the decade, in global rankings to recognise those companies which have demonstrated the greatest sustained creative excellence, based on winning and shortlisted work over the last 10 years.
We also continued to be recognised in independent research evaluation. In its March 2020 report, Gartner included four WPP agencies (AKQA, Ogilvy, VMLY&R and Wunderman Thompson) in its Magic Quadrant for Global Marketing Agencies, rating AKQA highest globally for both vision and execution.
Update to COVID-19 response
The significant majority of our people have been working remotely since March, with some recent re-opening of offices at reduced capacity in certain countries, involving very strict hygiene and social distancing protocols. As outlined above, we have ensured strong continuity of service to clients at a time when the need for our services and expertise has been greater than ever.
The latest level of office-based working in our main markets is as follows: US 1%, UK 3%, Germany 17%, China 77% and India 0%.
We have continued to work with clients, governments, national health organisations and NGOs to help limit the impact of COVID-19 on society, including our multi-agency support for the World Health Organization on a pro
