Ebert was named Webby Person of the Year on Tuesday with organizers of the Internet awards saying the film critic "raised the bar for online journalism and writing through his poignant and wildly popular blog, Roger Ebert's Journal."
JimCarrey.com won in the celebrity/fan site category, Kudrow's work in "Web Therapy" was honoured in the comedy series space and Rosselini's award came for experimental work in her "Green Porno" series.
Brad Pitt's "Make It Right" received a nod in the activism category and The Muppets earned a Webby for best viral video, among other things.
Among other winners, Next New Network's "Reel Good Show" will get the award for best variety video offer, "Texts from Last Night" will receive the mobile entertainment honour and College Humor's Amir Blumenfeld gets a Webby for best individual performance.
Judges for the awards included Martha Stewart, Matt Groening and Arianna Huffington.
Hosted by B.J. Novak of NBC's "The Office," the 14th Webby Awards ceremony on June 14 will feature winners and honourees delivering their by-now traditional five-word acceptance speeches.
