What stock today do you think is similar to GE or Sears? i.e. a “solid” large cap that everyone believed there was a promising future for.

I watched a conference with Buffett a few months ago. Basically he had a chart of the top 30 companies in the world by market cap 30 years ago or so. Not a single company of those 30 are in the list of the top 30 companies by market cap today.

So, which large cap stocks do you believe are our Sears or GE equivalent today? i.e. large cap companies that everyone believed there was a promising future for, that resulted either in mediocrity, steep decline in revenue/share price, or out right bankruptcy.
