• Nokia replaces CEO with Microsoft exec

HELSINKI – Nokia Corp. will replace CEO Olli-Pekka Kallasvuo with Stephen Elop from Microsoft on Sept. 21, the world’s largest handset maker said Friday, as it struggles to keep pace with smaller and more innovative rivals, particularly in the smartphone market.

With Nokia stock down more than 20 percent this year due to two profit warnings, Kallasvuo had come under increasing pressure amid speculation he would be ousted.

“The time is right to accelerate the company’s renewal — to bring in new executive leadership with different skills and strengths in order to drive company success,” chairman of the board and former CEO Jorma Ollila said in a statement.

Kallasvuo will leave as president and CEO on Sept. 20 and give up his seat on the board of directors with immediate effect and be replaced by Elop, who heads Microsoft’s business division.

Kallasvuo will continue to chair the board of the Nokia Siemens Networks unit in a non-executive capacity, the company said.

• Free Wi-Fi now at National Mall in D.C.

WASHINGTON – Free wireless Internet access has been added to the National Mall in Washington, D.C.

Officials say the city has installed 220 free Wi-Fi hotspots that are accessible by any compatible computer or device.

The D.C. government installed the hotspots along with the U.S. Department of Agriculture and the Smithsonian Institution. The private company Cisco donated the network hardware, and Level 3 donated the Internet services.

City officials say the free Wi-Fi will improve the National Mall for both residents and tourists visiting the many museums and memorials.

• eBay wins court round vs. Craigslist

SAN JOSE, Calif. – In a skirmish between two Internet heavy hitters with a tangled relationship, eBay Inc. has convinced a court that it was wronged by antitakeover moves adopted by Craigslist after eBay started encroaching on its online classifieds turf in the U.S.

A judge ruled Thursday that Craigslist founder Craig Newmark and CEO Jim Buckmaster violated their responsibilities to eBay — which bought a stake in Craigslist in 2004 — with changes they implemented that diluted eBay’s share from 28.4 percent to 24.9 percent and made it harder for eBay to sell the interest.

Craigslist made the changes in 2008 after determining that eBay had changed from a partner to a threat.

That shift happened after eBay launched a U.S. version of its Kijiji classifieds site — which competed directly with Craigslist — and started buying online ads steering Internet users looking for Craigslist to its own sites, Buckmaster testified in a nine-day trial.

The judge, William Chandler III of Delaware’s Court of Chancery, ordered Craigslist to reverse the steps that diluted eBay’s stake in Craigslist. However, he allowed another step that Craigslist took to keep eBay at bay to stand. That move made it harder for eBay to unilaterally name a director to Craigslist’s board.
