How did Linux become a mainstream embedded operating system?

" summary

Linux shrinks and ports: early wins are a few-hundred-kilobyte busybox, MTD drivers plus JFFS/JFFS2 for flash, and ubiquitous u-boot bootloaders, which let vendors ship devices like Axis webcams, TiVo DVRs and the Linksys WRT54G (which spawns WRT54G/OpenWrt hacks). Tooling matures from ad-hoc builds to reproducible systems with Buildroot/OpenEmbedded/Yocto. Real-time needs add PREEMPT_RT patches; Android pushes scale—over two billion Linux users and an estimated 250 million set-top/smart TV units per year.
