Can somebody tell me how this is different? I was under the impression that stations were under no obligation to continue their analog broadcast until even the original switchover date. In fact, the PBS station in town has already completed their switch to digital. Therefore, the new bill only seems to explicitly state something that was already possible with the previous bill. Am I missing something here?

In addition to worrying about the data being accessible, it might be prudent to look into filling the capsule with a noble gas to help prevent oxidation of the storage medium.
