Adsense for Video no longer making available the option to sign-up for video units, Google asked those who are currently displaying them to begin removing the video unit code from their pages. It promised to credit to their accounts any earnings they'd made from the units. Any leaderboard or skyscraper video units remaining on pages after April will direct visitors to YouTube and other video unit sizes will automatically convert to standard embedded YouTube players, said Google, stressing these players will not generate any revenue.
