The number of ad breaks on TV could increase after it emerged that the regulator is reviewing its rules.
Commercials may also become longer and product placement could occur more often in programmes as Ofcom considers changing the rules because traditional broadcasters are facing increasing competition from streaming services like Netflix and Disney+.
