Twitter said Tuesday that its opening up its TV ad-targeting technology to all U.S. advertisers that run national television spots and want to reach live viewers with synchronized in-tweet promotions.

Twitter, which had been calling the ad initiative "Twitter Amplify," markets the second-screen advertising play as an automated way to boost the impact of traditional broadcast advertising.
