McGowan abandoned the Chunky Mark persona in late 2010 and fully adopted the "Artist Taxi Driver" persona for his web blog on YouTube, where he films himself alone in his taxi between fares, often wearing dark sunglasses, and in which he rants passionately and emotionally about the news and issues of the day. The Artist Taxi Driver's official YouTube channel (still under the "ChunkyMark" name) by 2013 had thousands of videos made by McGowan, with almost 30,000 subscribers, and his most popular video viewed 220,000 times.
