There were a few television shows in the 1980s that showed how to make your home look better, but these usually included home improvement projects and not necessarily decorating. This show was called This Old House. It began airing in 1980 long before Martha Stewart’s show began.
Therefore, Martha Stewart was not necessarily the first lifestyle and decoration artist unless you don’t include home improvement shows. It is difficult to determine who started this craze. Martha Stewart is certainly one of the first.
She began her magazine first called Martha Stewart Living, but then she began her television show which took off. Then others began their decorating shows and now there are so many on television that you can’t turn on the television without seeing a decorating show.
