Adsense cleared the doubts on a long controversial topic that whether 2 adsense publishers can display their own ads on a single page or not? And this topic was long debated as Adrevenue sharing plugins for various platforms including WordPress, vbulletin etc. appeared.
Google clarified that Adsense actually allows more than a single publisher on a single page. Though clicks will be counted as separate for that particular adblock of that publisher and revenue will be divided as per click on the respective adblock. And even after allowing 2 publishers, number of adunits allowed per page will be same as before. No changes in it.
