Counter-Strike - Why did Defuse Mode trump Hostage Mode?

I look back to the game's earliest days to investigate why- despite hostage mode coming first- defuse mode eventually reigned supreme. I also question how things might have been different, and ponder what would be required for the same change to happen today. Oh, and if you think those pie charts with the made up numbers were bad- they were a lot worse without the numbers 0:00 - Intro 1:02 - Defuse VS hostage gamemode 2:23- Hostage's historical changes 5:04 - Why did people play the Counter Strike Betas? 6:26 - Good VS bad outcome determiners 9:04 - Early defuse mode 9:54 - What if?... 10:31 - Applying to the present day 11:19 - Now VS then
