BBC rapped over U2 and Coldplay
The BBC has been rapped for promoting U2's last album and a Coldplay tour.
The broadcaster's own editorial complaints unit ruled that a "U2=BBC" on-screen graphic to mark the launch of U2 album No Line On The Horizon was "inappropriate".
The BBC also breached guidelines with its "Radio 1 presents Coldplay" website, which included a link to ticket agents for the band's tour.
The volume of coverage given to the U2 launch last February - including a rooftop performance on Broadcasting House - drew criticism at the time.
Conservative MP Nigel Evans asked: "Why should licence fee-payers shoulder the cost of U2's publicity?"
Commercial radio body The RadioCentre also made an official complaint.
The BBC's complaints unit said the logo gave an "inappropriate impression of endorsement".
And a reference to the corporation being "part of launching this new album" in an interview that U2 frontman Bono gave to Radio 1's Zane Lowe was ruled inappropriate.
Further complaints about an edition of Jo Whiley's Radio 1 show and an online report of the rooftop gig were not upheld.
