Couple of factoids that might help answer that question:
Ministry Watch reports that the "Crystal Cathedral" can seat 2890, with 1000 additional seats/space for choir, ministry staff, etc. I think it's safe to say that the "congregation of about 400" mentioned in the article is an indication that membership has seriously declined.
A Businessweek article last week mentions that the "Hour Of Power" broadcast brings in 70% of the church's revenue, and conjectures that changing the locale of the broadcast (to the 1,200-seat St. Callistus Catholic church) would jeopardize the size of its television audience and further shrink the church.

Perhaps this is a members meeting. Actual attendance higher, official membership relatively low.
