Launch of iPlayer Radio
Later today, the new site will replace the one you've been used to. This is part of the launch of iPlayer Radio, which creates a single coherent experience for all BBC radio across PC, mobile and tablet.
It includes the release of the first bespoke BBC radio smartphone app (freely available from the Apple store at launch, other mobile platforms to follow). Mark Friend, Controller of BBC Audio & Music Interactive, has written in more detail about iPlayer Radio and you can read his post, and leave a comment, on the BBC Radio blog.
Everything you were able to do on the old Radio 4 and 4 Extra sites is possible on the new ones but the way you do it may be slightly different. The navigation bar at the top of the page lets you find programmes by Category, A to Z, Search and via the Schedule.
To listen to a programme that's live on air right now, click on the On Air tab on the left-hand side of the screen. This also shows the name of the programme that's currently on air.
The other tabs on the page showcase daily Highlights of programmes and clips you can hear online plus Factual, Drama and Comedy programmes.
We'd still really value any feedback you have on the new BBC radio sites and your experience of them on PC, mobile and tablet. Comments on this post are closed so we can collate all feedback about every station in one place, on the BBC Radio blog. I will read all of the comments on Mark Friend's blog post and if there are recurring questions about Radio 4 and Radio 4 Extra I will answer them in another blog post here later in the week.
The desktop sites will roll out over of the course of this afternoon, and we anticipate the iPhone app will be available to download for free from the app store by the morning. I hope you enjoy using them.
