Iris Wee was promoted in September to vice president of marketing, however the search continues for a replacement head of content.
Tham has overseen the marketing of the Singaporean telco's cable TV, broadband and mobile interests since joining from the Television Corporation of Singapore in 1996.
This year, she was instrumental in the acquisition of the EPL broadcast rights, and the launch of new channels on StarHub digital cable including Fashion TV, Sky News and Star Chinese Channel. David Tang, president and CEO of StarHub's agency DDB Singapore, commented: "Loke Kheng will be deeply missed.
She is a widely respected and liked marketer. Thankfully StarHub has a solid succession plan in place, and we look forward to working with them in the coming years."
StarHub renewed its contract with DDB for a further two years at the end of 2007.
