Z-24, a cooperative catalog database, has passed the 100 million household threshold. The shared information transaction file now has 750 participants.
When the database was launched in 1990, it contained information on 8 million households contributed by only six participants.
The database, which is run by Costa Mesa, CA-based Experian, also offers a variety of modeling any analytic services to participants, who are allowed to draw names – anonymously – out of the data pool.
