I recall that when My Network TV first launched, they tried English-language novellas, two hour-long episodes, each of a different series, five nights a week with each one having a definitive ending (usually 13 weeks/65 episodes).
Novellas have long been popular on TV in Mexico and South America (indeed, Univision's prime time schedule consists mainly of Mexican novellas). So, My Network TV thought they could adapt the novella format to English-language television.
English-language novellas produced in America were a colossal failure for My Network TV, but at least you have to give them credit for trying something "out of the box".
