Together, Kevin Rose and Alex Albrecht are akin to Oprah for a certain class of tech enthusiasts.

The weekly beta-testing and beer-guzzling show they have hosted for six years, “Diggnation,” adapted the television talk show format for the Web and helped prove that there was a business model beneath the anything-goes veneer of online video. Thousands of fans have attended live shows; some even crowd-surfed during a taping last spring at the South by Southwest, the technology and music festival in Austin, Tex.

Like Oprah, though, Mr. Rose and Mr. Albrecht have decided to direct their energies elsewhere. They announced on Monday that “Diggnation” will cease production in December, ending one of the Web’s most popular regularly scheduled series.

Their explanation for ending it: They’ve grown up, just like the Web has. “We started this show as kids,” said Mr. Albrecht, now 35. “Both of us came into Web video at a time when ‘Web video’ wasn’t even a word.”

Said Mr. Rose, 34: “There are other things, creatively, that we’ve started to do that are a little more fresh and exciting.”
