I think that both this article and the Wikipedia article are correct. The LA Times took the more human-centric approach to the story, which from a technical perspective was just 'how many and which characters can we cut out to maximize the 128 bytes available'. It also highlights the person (or the person who lead the team of people) who actually extended the SMS control channel to include text messages. I think that overall the story told by the LA Times is probably a lot more interesting to its readers than the tech behind it.
