The IBM issue ...
IBM are suppliers to the tournament and thus providing the service to the organisers, which the BBC are contracted with. There's no direct relationship between the Broadcaster and IBM.
Telenor are suppliers/sponsors to the ESC which is organised by the EBU which the BBC are a member of, so the relationship is one of subsidising a BBC organised event (remember Robinsons at the SPOTY a few years ago) therefore it's not permissable and counts as advertising or product placing.
