If you like, Video CD and DVD is a much fairer comparison.

Of course DVDs will come to an end at one point, but not the same way VHS did.
There is a long history of product introduction, and product sunset that supports the notion that DVD will disappear just like VHS did. First it starts with a newer better product being introduced. Then there is a period of co-existence where the new and the old get the same support. After a time, you see the extra content dropped from the older product as sales slide downwards, and the new product sales trend upward. Then the manufacturing support for the older product dries up as profits slide, and eventually the product is dropped. We already have two manufacturers who have or will stop making DVD players. We are already seeing extra content on Blu ray not found on DVD. All consumer product introduced in the last 40 years has undergone this type of lifespan. Cassettes to CD, VHS and Laserdisc to DVD, and now DVD to Blu ray.

VHS and DVD are both carriers of movies even if the technology was different. Whether it was on tape, or on a disc, they both carried movies to your house. They are both video formats, so it is quite a apple to apples comparison.
