It's been a while since Facebook launched the Ticker and now you expect that every user has this addition. The Ticker is placed on the right and includes the activities of friends that are currently held directly so you can anticipate possible. This is not the case and several users are wondering how this is possible. They discovered the reason behind this is because after some research shows that the ticker only appears if you have 100 friends or more. The social network is pretty strict with regard to this limit because once you fall back to 99 friends will immediately disappear Ticker.Activity
Although Facebook itself or in the help center shows that the functionality is only meant for people who reach a certain level of activity, nothing is said that this is actually a limit of 100 friends.
It is perhaps also true that those who currently do not have the ticker might not have been too sad. There is much criticism of the Ticker and it was recently announced that sponsored stories (advertising) will be emerge between updates.
