All streamable episodes of all past garden make-over programmes
around the world should have standardised tags with their
attributes. Then a way to search them by these tags. This would
enable people to watch those that best match their needs and
avoid those that don't.
The tags would cover the qualities that are often not included in
text descriptions or hard to search for as they are so common.
You'd discover useful programmes you never knew existed.
Essentially Pinterest/Instagram for TV programmes.
Could be applied to home improvement, and other subjects too.
The taxonomy would also be useful for web pages, YouTube videos
