"The availability of local content for use on mobile platforms is still a challenge, but I'm confident that we, in the mobile advertizing [sic] industry, can and will succeed in fostering a stronger content development focus on the continent," said Nyong'o in a statement.

Over the past two years, there has been a lot of talk about the mobile ecosystem in Africa, with recent reports pegging mobile subscribers in the region at more than half a billion.

InMobi's vice president of global research and marketing, James Lamberti, said Africa is a major market in the global mobile ecosystem.

According to an InMobi research network report released recently, mobile advertising impressions grew 19 percent in Africa in just 90 days. The report also said increased mobile Internet adoption delivered more than 250 million new monthly impressions.

InMobi claims to reach 50 million subscribers in Africa through nearly 3 billion ad impressions monthly. South Africa is the largest market, with 1 billion impressions and 20 million consumers monthly.
