The Screen Actors Guild and the American Federation of Television & Radio Actors have agreed to meet with the advertising industry over the industry’s proposal to study changing revenue models in the advertising biz.

SAG and AFTRA have scheduled a Saturday meeting to obtain further information about the proposal. The unions stressed in an announcement Thursday that the meeting is not a formal negotiating session.

The current contract covering commercials work by actors expires October 30. The meeting could be the first move toward granting the ad industry’s request to extend the contract for at least a year in order to perform the study.

Members of the negotiating committee for the unions have been leaning toward agreeing to an extension, in the light of the fast-changing landscape of advertising such as ads on cell phones.

The ad industry announced last month it would hire a consultant to perform the study even if the unions didn’t agree to provide funding for the study.
