A couple of weeks after Motorola announced it was halving its research unit, the company is now shuffling its executive lineup around the globe. According to RCR Wireless News, Motorola is replacing top executives in key markets as its share of worldwide cellphone sales falls to new lows:

"In an internal memo circulated last week and obtained by Crain's Chicago Business, Motorola named new leaders for its cellphone businesses in China, India, Europe and North America. The moves come amid growing doubts about Motorola's plan to turn around the business and spin it off as a stand-alone company."

The report pointed out that Motorola's global market share has plummeted to 9.7 percent, which is exactly half what it was one year ago. Analysts weren't particularly bullish about the latest moves either.

"If you keep losing share, how do you have the scale to compete in the longer term?" said Ping Zhao, an analyst in New York for CreditSights, in the report. "One reason they made money in the past is they were so much bigger than everyone else."
