Between August 2008 and March 2011, Topolsky was the editor-in-chief of the technology blog
Engadget. Since 2009, he has been the technology correspondent for
NBC's
Late Night with Jimmy Fallon, and then
The Tonight Show Starring Jimmy Fallon. In March 2011, he resigned his position at
Engadget. Following his departure from Engadget, Topolsky began a new site called
This Is My Next, a temporary home for him and his ex-
Engadget colleagues as they built a new technology network. Like Engadget, the website included a wide variety of technology news, reviews, and editorials. The website name is a play on a phrase Topolsky often says when reviewing a device that he especially likes (e.g. "This is my next phone."). Topolsky's team at
This Is My Next included former
Engadget editors and contributors including Paul Miller,
Nilay Patel,
Joanna Stern, Chris Ziegler, and others. On July 18, 2011, Topolsky announced on
Late Night that he and his team were developing a new permanent network called
The Verge.
The Verge launched on November 1, 2011, with Topolsky as the founding editor-in-chief. In April 2015, Topolsky started
Tomorrow, a weekly podcast about current trends in technology, news, and culture. Each episode of
Tomorrow features cohost Ryan Houlihan and a special guest, ranging from Google designer
Matías Duarte to Topolsky's wife. In 2016, Topolsky pursued initial funding for a new digital media outlet. The company is titled Independent Media and launched its first publication,
The Outline, on December 5. In 2023, Topolsky was hired by
Robinhood to launch Sherwood Media, a website dedicated to "deliver[ing] actionable, illuminating news on the markets, business, tech, and the culture of money in a way that's authoritative, engaging, and speaks in the language of this moment". As of 2025 Topolsky is Sherwood's editor-in-chief and president. ==Music==
