Scale of Australian Nielsen Twitter TV ratings under scrutiny

According to a story on Australian media news site Mumbrella, Twitter has consistently refused to release a public number on its active Australian users. Agency sources, the site says, claim that its sales team is using a figure of around 4m users, while academic studies apparently place the figure much lower at 2.8m.

Scott Gillham, head of NTTR, told Mumbrella that while the audience number looked at only Australian accounts, it was up to Twitter to release the number of its universe.

Gillham also refuted claims that Nielsen had dropped the price of NTTR in Australia after only two TV networks signed up to the new service.
