As so many Americans are dog owners, it is incredibly disruptive to daily life when TV commercials contain a ringing doorbell. Companies producing commercials should be banned from putting doorbells in their TV commercials. This is especially compounded when families with young children that may be sleeping also have dogs that react to TV-based doorbells.
This could be extended to any television programming, but as commercials are run multiple times over the course of a few hours, for weeks at a time it is really an issue with TV commercials more than the programming.
