THE DEAL: Twitter has bought TweetDeck, a London-based startup that helps people read, write and organize the short messages posted on the online network. It will keep the service going.
THE MONEY: Twitter declined to give financial terms. Published reports have pegged the price at around $40 million to $50 million.
WHAT'S IN IT FOR TWITTER? TweetDeck is home to many of Twitter's so-called "power-users," such as celebrities, businesses and other frequent and influential contributors. Debra Aho Williamson, principal analyst at eMarketer, says Twitter needed to make sure these users are "staying in the fold" _ and seeing its ads.
