Washington Journal is probably classed as an import since its a simulcast of the CSPAN network, and as such the output isn't under the control of the BBC, not directly anyway. I presume they contribute something towards the programme as its probably safe to assume they don't simulcast for fun.
I believe with regards to Skype, Ofcom used to consider it a form of product placement, as per Broadcast Bulletin 190 from 2011:
https://www.ofcom.org.uk/__data/assets/pdf_file/0013/45040/obb190.pdf ( pages 27 and 28 ) posted:
Under the Communications Act 2003, Ofcom has a statutory duty to set standards for broadcast content as appear to it best calculated to secure specific standards objectives ... Rule 9.5 of the [Ofcom Broadcast] Code, prohibits the undue prominence of products, services or trade marks in programming. Such undue prominence can arise if there is no editorial justification for referring to the product(s), service(s) or trade mark(s), or from the manner in which they are referred to.
Ofcom noted that [the broadcaster] had received no payment or other valuable consideration from Skype for reference on air to its brand. We also noted that, while Skype‟s Broadcast Terms of Service required broadcasters to refer to Skype in programmes that included its video call service, they also acknowledged the primacy of statutory provisions relevant to individual broadcasters.
... Ofcom reminds broadcasters that references to material broadcast „via webcam‟ or „via video link‟, for example, are unlikely to raise issues under Rule 9.5 of the Code, but any visual and/or oral brand reference should be both editorially justified and brief.
Of course it was a different environment in 2011 and these days thanks to product placement and the fact the likes of Skype and Facebook video and Whatsapp and everything else means it isn't particularly uncommon to see on the TV somebody doing a two way over a Skype internet connection - the bad "framing" of the shot and the sometimes unique lighting thanks to domestic lights is usually the giveaway, not a humongous Skype logo floating around on the video
