Enough people enjoy watching it to make it profitable TV.

A lot of this psuedo-educational crap is primarily entertainment
dressed up in a way that people find interesting (home-making and
DIY) and viewers can easily convince themselves that the time
they are burning on it is in fact self-improvement like reading
an educational book.

It isn't. You may pick up the odd useful point but that isn't the
main idea and as a means of picking up valuable info it's
massively inefficient (in terms of gain per hours viewing).

These are just the new cookery programmes where Gary Rhodes pours
in another gallon of lard for your entertainment while you peck
at your TV dinner. It doesn't matter that if you ate that stuff
he's making it'd give you a coronary quicker than your staple
diet of microwave chips will, hardly anyone who watches these
shows actually does any cooking but they can justify dribbling
their lives away by thinking that they are learning cookery.
