E-books are the fastest-growing part of our business, with the sale of digital products increasing exponentially each year. IPG's decade of experience in the e-marketplace, industry-leading access to sales channels, expertise in both traditional and digital marketing, cutting-edge digital warehousing, Adobe Content Server DRM-protection software, and reporting services equip client publishers to take full advantage of every opportunity the market has to offer.
IPG sold its first e-book in 2001. Since then we have actively contributed to the transformation of the e-book from fad to industry fundamental. Our very active participation in the digital movement means that we—and our client publishers—have kept pace with the unprecedented rate of change in the industry. Hundreds of small and medium-size publishers now benefit irom IPG's knowledge of the digital marketplace. Digital sales now make up an important part of total publisher revenue.
IPG has a close relationship with all major e-book vendors, ensuring that client publishers can capture the full sales potential of the Apple iBookstore, Amazon Kindle, Barnes & Noble Nook, and Sony e-reader devices and stores, among others. IPG also works with more than 100 e-book affiliates and re-sellers, ensuring that client publishers have maximum exposure to the digital marketplace in the United States and around the world.
IPG ensures that all client publishers have access to a host of print, online, and social media marketing initiatives to promote the sale of their digital editions. Moreover, we act on an insight that is as true today as it was 10 years ago: In most cases, the successful sale of a digital title is tied to effective promotion of the print edition of that title. IPG's core competency in physical book distribution means that our client publishers get the best of both worlds.
IPG publishers enjoy a streamlined e-book submission, conversion, warehousing, and business intelligence solution. The submission of a PDF is all that is needed to for a title to reach the digital marketplace: IPG handles the e-book file conversion, metadata creation, quality control, and vendor relations for all digital editions while answering any questions publishers may have along the way. IPG also utilizes the most trusted encryption software in the industry, Adobe Content Server 4.0, to apply DRM (Digital Rights Management) protection to every e-book file we distribute at no cost to our client publishers.
After publication, our clients receive anytime access to their finished e-book files, which are stored on IPG's secure servers. IPG also offers an online reporting tool that keeps publishers apprised of the performance of their digital titles and allows them to analyze sales by factors including customer type and e-book format.
