Nipper, the dog, was used to advertise radios
television
O variety shows
O record players

It should be radios

It should be radios or television because i feel like television would be accurate to watch and listen to the dog

Photography has changed its subject matter quite a lot over the past few years. in the 1800's, it was considered normal for families to have  post mortem photos of their loved ones, and now that would be completely unacceptable. i think that photographers have always pushed boundaries and have been eager to capture everything, it is just society that changes their boundaries.
