That statement was made about 18 months ago. It is no longer true. Microsoft's revenue in FY 1998 was $14.48 billion as per https://news.microsoft.com/1998/07/16/microsoft-posts-record... .

Last 12 months rev for G and M are $75 and $85.3 billion per Google finance.

edit: M's revenue had actually decreased $8 billion over the prior 12 months.
