Adobe and Nielsen have teamed up to deliver an online media rating system similar to that in place for measuring the success of shows on TV. The new tool will, for the first time, measure the engagement of online TV, videos, games, audio and text products, across a diverse range of devices and platforms including desktops, smartphones, tablets, game consoles and over-the-top boxes. The collaboration will see Nielsen’s digital audience measurement products combined with Adobe Analytics and Adobe Primetime.
