Church (and other) bells

This struck me at work the other day so I thought I’d hand it over to you guys:

After living in close proximity to churches, etc. for a good potion of my life, I have noticed that there seems to be a faily common 8-note sequence which is often played twice on the bells to mark the hour. I’ve also noticed this pop up as a popular tune on electric doorbells. What is the name of this little song? And why did it become the industry standard for chimes, hourly or otherwise?

Probably Westminster Quarters as made famous by Big Ben
