What does the Konami code actually do?

I know it's up up down down left right left right B A but I've never understood where it came from or which games still react to it. Is it just a meme now?

Up, Up, Down, Down, Left, Right, Left, Right, B, A. It started as a dev cheat in Gradius (gave you full power-ups) and got famous from Contra on the NES, where it gave you 30 lives. Since then lots of games and even websites hide an easter egg behind it, so what it does depends on where you enter it.
