Twitter debuts ‘Happening Now’ to showcase event tweets

Twitter is debuting a new feature today called 'Happening Now' aimed at giving newcomers groups of tweets about a topic. 'Happening Now'
is similar to Moments, except 'Happening Now' will take users
to a dedicated timeline of tweets
related to the event at hand. The new feature is only available for sports at the moment but it will move to other categories in the future.
