Jay Z brought along some (very) famous and influential friends for this week's re-launch of Tidal, his high-fidelity music streaming service. The rapper's strategy to reach the most prospective subscribers began with a mysterious viral campaign, which saw artists with a combined 156 Twitter million followers change their avatars blue and declare #TIDALforALL in similar tweets.
Several big social gets for Jay Z in his rollout campaign include Alicia Keys (21.46 million Twitter followers), Coldplay (14.4 million), Nicki Minaj (19.1 million) and Rihanna (43 million), respectively. Jay's wife Beyonce, who has 14 million followers but has not tweeted since August 2013, also blued-out her avatar, as did Kanye West (11.8 million) and Usher (10.2 million). Most included the message "History will be made in 5 hours" and a 30-second promo for a live stream event.
