NPD Intelect reports that Handmark maintained its position as the best selling mobile software vendor last quarter.

According to the research firm, Handmark held the number one retail mobile software spot with 35% of the market. The NPD ranking is based on actual retail sales revenue as reported by 80% of the nations leading software retailers and includes online packaged software sales by those retailers.

In addition, more than one in every three retail dollars spent on mobile software went to Handmark published titles in December. Handmark also had 8 of the top 20 best selling titles in the category. Even though the market size declined by 20% in 2003, Handmark sales grew 37% over the same period year-over-year.

Handmark titles, which are for Palm OS and Windows Mobile for Pocket PC based handhelds, include Rand McNally StreetFinder, Tetris Classic Game Pak, Rand McNally Road Atlas, PDA Bible, Trivial Pursuit and other family board games, and PocketMoney.
