TWiT.tv, which is the operating trade name of TWiT LLC, is a podcast network that broadcasts many technology news podcasts, founded by technology broadcaster and author Leo Laporte in 2005, and run by his wife and company CEO Lisa Laporte. The network began operation in April 2005 with the launch of This Week in Tech. Security Now was the second podcast on the network, debuting in August of that year. The network hosts 28 podcasts (as of July, 2020) though the number had fallen in half to only 14 regularly scheduled shows by January 2021. Podcasts include The Tech Guy, This Week in Tech, This Week in Enterprise Tech, Security Now, FLOSS Weekly, and MacBreak Weekly. In addition to shows on technology news, TWiT also has podcasts like Hands-On Photography".

TWiT founder and owner Leo Laporte, in an October 2009 speech, stated that it grossed revenues of $1.5 million per year, while costs were around $350,000. In November 2014, during an interview with American Public Media's Marketplace Leo Laporte stated that TWiT makes $6 million in ad revenue a year from 5 million TWiT podcasts downloaded each month, mostly in the form of audio, and that 3,000 to 4,000 people watch its live-streamed shows. On March 18, 2015, prior to the filming of This Week in Google, Leo Laporte stated that TWiT expects to make $7 million in revenue in fiscal year 2015, and made "almost" $10 million in revenue in 2016.

TWiT gets its name from its first and flagship podcast, This Week in Tech. The logo design originated from a traditional logic gate symbol of an "AND gate" turned on its side. Voiceovers are provided by Jim Cutler.
