PARIS, June 28 (Reuters) - French advertising group Publicis (PUBP.PA: Quote, Profile, Research, Stock Buzz) and software group Dassault Systemes (DAST.PA: Quote, Profile, Research, Stock Buzz) will create a joint venture in 3D online marketing in a bid to boost advertising sales, the two companies said on Thursday.

The Paris-based venture named 3dswym -- an acronym for 3DSee What You Mean -- will be 51 percent owned by Publicis and 49 percent by Dassault Systemes and will allow marketers to reach consumers directly and to create and adapt new consumer goods together, the joint statement said.

Publicis is making a push into digital advertising, which is growing faster than traditional advertising.

Publicis Chairman and Chief Executive Maurice Levy told a news conference it was difficult to quantify the venture's potential revenue.

But if it took "just a little piece" of a global market estimated at over $50 billion "we would not be unhappy", he said.

Publicis recently acquired U.S. interactive and direct marketing company Digitas for $1.3 billion and earlier this month announced the purchase of a 49 percent stake in interactive marketing agency Business Interactif BUSI.PA.
