But the Insights blog at Dice.com counters that TIOBE "has hammered on C for quite some time. Earlier this year, it again emphasized how C is 'hardly suitable for the booming fields of web and mobile app development.' That being said, job postings on Dice (as well as rankings compiled by other organizations) suggest there's still widespread demand for C, which can be used in everything from operating systems to data-intensive applications, and serves many programmers well as an intermediate language."
i-programmer suggests this could just be an artifact of the way TIOBE calculates language popularity (by totaling search engine queries). Noting that Assembly language rose into TIOBE's top 10 this year, their editor wrote, "Perhaps it is something to do with the poor state of assembly language documentation that spurs on increasingly desperate searches for more information." Maybe C programmers are just referring to their K&R book instead of searching for solutions online?
