COLOR-different modes?

Question–> Different color modes like?

sRGB([COLOR=black]IEC 61966-2-1)[/COLOR] Adobe RGB NTSC9153

Which is the most popular(widely used color mode for web:)

for the users?
for the web designers?
for the programmers?

I read its the sRGB, because many monitors today are built or come with that as a default, but I just want to check this out with you guys and gals =)

reason:: designing a website and want to know what color mode is better supported for my jpegs.
I’m also hoping to make this a constant thread about color in the digital age…
