Twitter on Monday announced a partnership with Bloomberg Media to launch a 24-hour streaming news service — one of a dozen new content deals Twitter has entered to drive user engagement. CEO Jack Dorsey and a group of top executives announced the slate of programming agreements — which include concerts from Live Nation, sports from Major League Baseball and the WNBA, and a morning news show from BuzzFeed. Starting this fall, Bloomberg will offer a live, streaming 24-hour, exclusive news feed that will include user-generated news content.
