If it wasn't already clear that Twitter is serious about monitoring TV trends, the company just proved it by acquiring Trendrr. The deal gives Twitter new tools for both tracking social network activity during TV broadcasts and delivering that information to advertisers and media producers. While the two companies aren't specific regarding their plans, Trendrr is scaling back its operations: its Curatorr service will keep going, but it will stop taking customers for its Trendrr.TV engagement tracker. It will be some time before we see the results of the acquisition, but the increasingly tighter links between Twitter activity and TV suggest that the buyout could prove worthwhile in the long run.
