Dive summary: 

• Amazon has signed a deal with Viacom to bring thousands of television shows and hundreds of movies to the online retail giant's streaming service Instant Video. 
• The deal increases the tension between the three big players in online streaming--Netflix, Hulu and Amazon. Some of the titles like "Dora the Explorer" were previously exclusive to Netflix before the Amazon Prime deal. 
• The financial information from the deal have not been disclosed, but a source close to the deal said this is the most Amazon has paid for any Prime content and that more than 4,000 TV shows are included in the deal.
