Singapore Press Holdings (SPH) is celebrating its 30th anniversary this year.

As part of its celebrations, the media organisation is holding a monthly contest giveaway from February to August.

Prizes include shopping vouchers and exclusive branded wine sets. To qualify for the contest, "Like" the SPH Facebook page or "Follow" SPH on Twitter (@official_sph). You will also have to answer the following question and send your answer with the subject title "SPH turns 30" to limcher@sph.com.sg, along with your name, identification card number, e-mail address and contact number. Three Takashimaya vouchers worth $50 are up for grabs. Contest closes on Feb 21.

This month's question is: When was SPH incorporated?
