IGN has appointed Shepperson from Reader's Digest, where he was sales director, to join its growing UK commercial team.
In his new role, Shepperson will report to commercial director Adam Hopkinson, taking responsibility for building revenue and leading creative innovation across IGN's core websites.
He will also work closely with head of games Dominic Barry and film sales manager Shivali Ramanandi to deliver campaigns for its IGN's roster of advertisers, which includes Alfa Romeo, Channel 5, Debenhams, HTC, and Porsche.
Adam Hopkinson, commercial director for IGN Entertainment UK, said: "With over a decade of experience at the highest level, Chris will take an important role in building our reputation for creative and engaging campaigns that deliver fantastic results."
Before working at Reader’s Digest, Shepperson spent more than a decade with Bauer working in roles including head of market for its men's entertainment titles helping develop Empire, Mojo, Q and Kerrang! into multi-channel brands.
Other recent appointments at IGN include Ramanandi, who joined in January, Hopkinson in March, and Michael Hand who last month took the newly created role of head of consumer and lifestyle.
Hand joined IGN from The National Magazine Company, where he was has been head of digital for Men's Health for five years.
IGN Entertainment claims to have an audience of 5.5 million men aged 18 to 34 across its digital portfolio, following the acquisition of Hearst Digital's games and entertainment portal UGO in May. It claims to receive 4.5 million unique visitors a month in the UK.
In News Corp's most recent results, its "other" segment, which includes IGN Entertainment, alongside MySpace and other digital business, made an operating loss in the first three months of 2011 of $165m (£101m).
While the losses were primarily blamed on lower advertising and search revenues at MySpace, which News Corp sold last week for $35m last week, it is understood that IGN is a profitable business.
