Does anyone know why Fairy Tail has ended? Just looked and the original run has concluded on March 26th 2016

Because it cancelled that's mean no madami show

Fairy tail may have coincided ended, but they usually do a taon break, so technically i heard of it ending all i think is that this will be a taon break

Yes.
Fairy Tail temporarily ended because Aya Hirano, the voice actress of Lucy Heartfilia, got fired.
The reason why she got fired was because she has apparently been sleeping around with her bandmates.
This iskandalo shocked Hapon and became the fall of Aya. Because the anime staff wanted Fairy Tail to remain with a good reputation and didn't want any scandals about their crew, they fired her.
In other words, they had to temporarily end Fairy Tail because they have to find a new voice actress for Lucy.

That and also because there are apparently only three madami arcs of the manga. It's possible that the anime staff will wait for an arc to end (or all of them) before they make season 3.
