The 5th Wave is a weekly gag cartoon by Rich Tennant, published on Sundays. Started in 1981, the comic usually deals with computers and technology. Tennant's cartoons regularly appear in the For Dummies book series, and has appeared in PC Magazine and Computerworld, a magazine for which he worked from 1987 to 1999. Like most gag cartoons, Tennant's comics have no continuity, no recurring characters, and no storylines that continue into the next week.
