Why the pill is the most popular birth control?

I’m just wondering why the pill is the most popular birth control is it because it’s easy as you take it orally and don’t have to have any insertion as people don’t like the idea of a doctor doing a procedure as it’s an invasion? Or is it cheaper for some people to have the pill? I feel a long acting inserted birth control would be cheaper in the long run as you don’t have to have any checkups during it and ones it’s paid for it’s paid for for years at a time? I’d really like to know everyones thoughts
