SANTA CLARA (AP) — Hewlett-Packard is selling its webOS software to South Korean electronics company LG Electronics, securing a new home for a technological orphan. The deal announced Monday rids HP of the centerpiece of its ill-fated, $1.8 billion purchase of Palm Inc. three years ago. HP used webOS as its springboard into the smartphone and tablet computer market in 2011, but quickly scrapped the mobile devices running on the software amid disappointing sales.
