But being more popular is a reason groups will pick it. See Emacs's discussion on moving away from BZR [0]. While there are some people that like HG, Git popularity brings some benefits with it. A larger user base and a large number of companies using it mean that there will be more investment in the tool. So there is a variety of companies that invest in it. There is a smaller chance development will stop on Git compared to HG. So basically the Emacs team concluded they don't want to be stuck with another BZR, and Git seems like a safer choice. A variety of companies have bet on HG, but decided they needed to support Git along side it to get more sales (Fog Creek and Atlassian). I feel like Github was the deciding tech that made Git the more popular code. There are a number of other companies supporting HG still, so it won't go away anytime soon, but it's hard to say if it'll be here as long as Git.
