SFM Media Corp., New York, resigned as the media planning and buying agency on financially beleaguered G. Heileman Brewing Co. account. The account, which initially billed $30 million-plus when SFM first picked it up three years ago, dwindled to the a point where it is projected to be less than $10 million next year. Heileman is in the process of restructuring and SFM was not able to work out a compensation agreement to continue servicing the account. W.B. Doner
, Baltimore, handles creative.
