But Twitter wants to keep its advertising business strong, and information like the data provided by Nielsen could provide a signal to marketers that their investment will pay off.
"Advertisers will not continue to do business with us, or they will reduce the prices they are willing to pay to advertise with us, if we do not deliver ads in an effective manner," Twitter said in its IPO documents.
Twitter has already partnered with TV broadcast networks like CBS, Fox, Bloomberg TV and BBC America for its Amplify advertising program. The program lets broadcasters place video from shows in users' feeds, along with advertising.
Nielsen's Twitter TV Ratings are available for TV programming across more than 215 English-language U.S. broadcast and cable networks, Nielsen said. The company is also working with Twitter to measure tweets around Spanish-language networks.
