ReCode, the news website led by the veteran journalists Walt Mossberg and Kara Swisher, is being acquired by Vox Media, a deal that reflects the turmoil among digital organizations focused on covering the tech industry.

The all-stock deal, financial terms of which were not disclosed, will give ReCode access to a wider audience, something it has struggled to build since the site split off from The Wall Street Journal about a year and a half ago. Both Mr. Mossberg and Ms. Swisher plan to stay with ReCode after the merger.

The purchase of ReCode, which was announced by the companies on Tuesday, is just the latest significant move involving a digital media start-up in the past few months. In March, Gigaom, which had been one of the early sites dedicated to coverage of Silicon Valley, abruptly closed after nine years because of financial problems. (It said Tuesday that it planned to restart in August after being acquired by the start-up Knowingly Corp.) Circa, a news aggregation start-up, is trying to sell itself to a larger media organization after failing to raise more venture capital, according to two people familiar with internal matters, though recent talks with companies like Twitter have fizzled. And Pando, another technology blog, has struggled to attract a large following despite a splashy introduction announcing prominent writers.

Before its split from The Journal and its parent company, Dow Jones, ReCode was run as a site called AllThingsD, which, since its founding in 2007, had steadily built a following among technology executives. The site grew out of a popular conference business that became known for hosting tech luminaries like Steve Jobs and Mark Zuckerberg. The conference business continued to grow and was an attractive part of ReCode’s portfolio for Vox.
