I covered the majority of Sky things here in the overnight report. Of other mention is the solid rating for Senna before the race day coverage, whilst The F1 Show did appallingly on the Friday evening after practice.
The race coverage on BBC One from 15:00 to 18:15 had an official rating of 5.25 million viewers, up 80,000 viewers on the overnight average.
