World Cup TV ratings suffer from good weather

The viewing figures for the France-Switzerland match were a record-breaking 1.5 million viewers. However, it is not possible to determine exactly how many people watched the match between Switzerland and France. The reason: those who watched the match on a big screen, in a sports bar or another public place were not included in the viewing figures. For Wednesday's Swiss national team match, the difference can be up to half a million viewers, reports the NZZ with reference to Holger Walther, Head of TV Research at Publica Data, which records the viewing figures on behalf of SRG. Normally, the deviations are not relevant - due to the beautiful summer weather and the match times immediately after closing time, a larger deviation than usual must be assumed.
Viewing figures are collected using 1000 Telecontrol meters, which are distributed in households according to social demographic criteria. The measured values are then extrapolated to the audience share. It is a long-known problem that the audience share figures are usually too low. There is currently no reliable method for eliminating the error rate.
