Since April, Twitter had announced Promoted Tweets - Twitter's new system to make money online .This was twitter's first business ad revenue model , and that was supposed to be in search results .However may be it didnt turned big or for any other reason the second phase of twitter's revenue model started - Promoted Trending Topics.
Toy Story 3 has now created history [ If twitter continues this plan ] which is the first sponsor promoted by Disney/Pixar. As you can see in the right hand toolbar of Twitter.com, at the bottom of the Trending Topics area there is extra topic , "Toy Story 3." Next to it is a big ugly yellow box shouting out PROMOTED - and clicking on it takes you to a search results page to see what people are saying about Toy Story 3.
Regarding the prior sponsored tweets model , i didn't see even a single of them ! Might be , depending on the location . But trending topic means a lot more and twitter could earn a lot more - in Millions or Billions ? And once a topic is a trend , everyone talks about it and creates a massive Buzz . Did you check your twitter account today for this promoted trend ?
