Mediaset forced to rename ‘El Rosco’ segment after trademark dispute

Mediaset's Telecinco prepared a new game‑show format called “Rueda la letra,” which would include the classic final round known as “El Rosco.” A court ruling confirmed that the trademark for the name belongs to ITV Studios, the producer of the rival programme Pasapalabra aired on Antena 3.

Because Mediaset does not own the name, it must refer to the round as a generic “prueba final” or another label. The dispute has led to legal actions by MC & F and Antena 3 to block Mediaset’s use of a similar format, and the name change caused confusion among viewers, prompting a correction on the programme’s casting website.
