Just for yuks, I’ve been looking at the major online comic strip services. As far as I can tell, there are basically three big ones. All include daily comics by email.
Comics.com — Run by United Media. $12/year for the basic paid package. Comics available include Peanuts, Get Fuzzy, and Dilbert. Lots of mainstream strips, along with a few oddballs.
DailyInk.com — Run by King Features. $15/year. Comics available include Mutts, Zits, Zippy the Pinhead, Spider-Man, and Prince Valiant. Generally includes more adventure strips than the other services.
MyComicsPage.com — Run by uclick. $12/year. Includes Foxtrot, Doonesbury, and a bunch of others. Mostly mainstream humor strips.
