The company continued using the ONED series of production codes, releasing as many as 30-40 videos per month, until ONED-999 appeared on June 19, 2008 when it switched to a new code series starting with SOE-001. Compilation videos which re-mix previously released material use production codes of the type starting with ONSD-001. In addition, S1 videos intended "for rental only" carry different codes. Original videos are labeled 5ONE-xxx or 5SOE-xxx and compilation videos follow the scheme 5ONS-xxx, where the "xxx" portion corresponds to the 3 digits of the same "for sale" videos. In the 2006 and 2007 AV Open contests based on video sales, the S1 entry took the First Place Award in both years. The S1 nominated video in the 2008 AV Grand Prix (based on sales and fan votes), won the GrandPrix Stage Highest Award and also the award for Best Package Design as well as the Press Award and the Dealer Award. At the 2007 Vegas Night awards, the S1 video "Hyper-Risky Mosaic Mihiro" won for Best Title and the top 4 places in the Best Actress category were taken by S1 actresses with Akiho Yoshizawa taking 1st Place. The studio also dominated the 2009 AV GrandPrix Awards winning the top GrandPrix Award in addition to taking the DVD Sales Award, the Retailers Award, Best Package Design Award, and the Best Featured Actress Video Award for "Double Risky Mosaic, Rio & Yuma".
