The last programme website to move across is one of our most popular - The Archers, which consistently receives more 'listen again' requests per month than any other BBC radio programme. A site tour takes you through the features page-by-page.

Where should you start?

If you're an Archers newbie who has always been intrigued by the happenings in Ambridge but never taken the plunge, then start with our short introduction, kindly read for us by Archers fan Stephen Fry. And then listen and explore the links from the latest episode panel on the homepage, to find out more about the characters and locations in the current storylines.

We've slightly enlarged the top right 'Find a Programme' panel, in order to present the link to all current Radio 4 programmes more clearly. The top picture promotion area has therefore been slightly reduced and, in order to preserve the image shape, we've moved the text to the bottom.

Thank you for your comments. While we're pleased with much about the new site, we always expected to continue work after launch.

Firstly, I'm sorry that so many of you experienced technical problems over the weekend. There were publishing problems on Friday afternoon which affected the availability of radio programmes. We're aware of another problem on Sunday morning which affected our new programme pages for a short time. It isn't any consolation to know that these failures weren't confined to Radio 4. I share your frustration.

I'd also like to pick up a few of the main issues raised in your feedback.

We're now ready to reveal the new Radio 4 website design. These annotated screenshots take you through some example pages from the new site with an explanation of their main features. Let me give you some background to this work which is one of the most complex redesigns in the BBC portfolio.

The design takes the colours and shapes of Radio 4's brand toolkit as its starting point. Our team worked with this toolkit to create a design that adds depth and impact to our programme pages, without distracting from the content - white background space and a subtle emphasis of the information hierarchy help to present the programme information clearly. Agreeing a design route is usually the point at which all stakeholders want to have their say and this project followed that honourable tradition.
