On my phone only I typically consume about 17GB of data each month on average. This is almost entirely music streaming sprinkled with a new ROM download about once a month.
My home Internet connection likely uses more than 500GB or more a month. I purchase games, delete and re-download games as I want to play them. I do not have Cable or Satellite TV so all my media is through streaming from Hulu, Netflix, or Amazon Prime. In addition to this I torrent a fair amount of Anime on a regular basis at 1080p quality so a season is typically around 20GB.
