A key internet advertising trade group has recommended a new set of ad sizes that are larger than standard web banners.
The Interactive Advertising Bureau (IAB) - whose members include MSN, AOL Time Warner and Yahoo - has created what it calls a 'Universal Ad Package'.
The package features the new large ad size as well as three sizes the group had previously recommended.
A spokesman for the IAB said the package would make web advertising simpler and more cost-effective.
The organisation said in a statement that the new sizes were created in response to advertiser demand for simpler, more efficient units.
It said it would now solicit industry feedback on the Universal Ad Package.
IAB members have agreed to offer the new unit and package to advertisers.
AOL has already been working with improving services offered from static ads as part of its bid to kill unpopular pop-ups from its site.
