Partially true, but also they wouldn't invest in something that lasts forever (without it costing an absurd amount of money or the subscription requirement). I like this video that shows the issue pretty well. (TLDW: Communist Germany made glass so durable it didn't break as a product to sell to the west. No company would purchase it though because they made most of their profit from selling replacements. The glass is now what we call Gorilla Glass, which is really only available on phones, which are designed to be replaced every few years anyway.)
100 years ago there was a meeting amongst lightbulb manufacturers that all collectively agreed to only design light bulbs to last about 1,000 hours. They were known as The Phoebus Cartel and Included Phillips and GE. Up until this agreement lighbulbs were typically lasting up to 2,500 hours. The manufacturers essentially created the concept of planned obsolescence because people weren't buying as many lighbulbs as they wanted and it was decided to stop making longer lasting bulbs with higher costs. The whole thing started falling apart (competition of non members that were making bulbs, but they were all small operations, as well as patent expirations that GE had) and the start of world War two pretty much broke it up, as the Cartel couldn't keep everything regulated and tested due to all the travel restrictions and such. But it still remains as the first global wide creation of planned obsolescence.
Extra fun fact: the common light socket screw design/size has remained the same since 1880.
That is mostly a myth. They did agree of the lifetime, but it wasn't planned obsolescence like people act. The lifetime of a bulb is directly related to how bright it is. If you make a really dim bulb it lasts a long time, which is how that one in the firehouse is still alive. It's so dim it's effectively useless. The group met to decide on a luminosity target, which also is a lifespan target effectively.
Not if you read/believe most of the info on the wiki. US government fined GE over it in 1949.

No, even the wiki (under "purpose") says the myth is probably not true. It was a cartel though, and therefore illegal in many/most places. It just wasn't because the planned obsolescence. Lowering lifespan also led to selling more bulbs though, so it was useful for that.
