When to use it

Means "ever since A, things have been different," and stresses that A was a turning point that changed someone's life or habits for a long time. Example: 犬いぬを飼かってからというもの、毎日まいにち歩あるくようになった (ever since getting a dog, I have walked every day). Used when looking back on a big change.

Nuance

Emotional and reflective; the speaker feels the change deeply. The second clause describes a continuing state that has lasted until now, not a single event or a future plan. Slightly written but common in speeches, essays and serious conversation.

Compare

てから just gives order: 食たべてから出でかけた. て以来いらい means "since" and is neutral: 卒業そつぎょうして以来いらい会あっていない. てからというもの adds the feeling that the change was big and lasting. を境さかいに marks the turning point itself, often for social trends.

Tip: The main clause should describe a lasting change (ようになった, すっかり変かわった). A single event after it sounds wrong.
