A Twitter Party is a 1-hour event hosted on Twitter and attended live by invited guests /influencers.

Much of the content consists of a series of themed questions that tie into your marketing message,
as a way to engage attendees. Influencers answer the questions (and win prizes!).
Content tying directly to the product/show, including screenshots and quotes, are also peppered throughout the party.
All participants utilized the custom hashtag, which tracks reach and engagement.
